oxide(CoFe2O4)electrode material for supercapacitors has beensynthesized via a chemical co-precipitation method using aluminum nitrate(Al(NO3)3)as a precursor ofaluminum oxide(Al2O3)hard template.The as-prepared CoFe2O4materials were spherical-likenanoparticles with diameter of around25nm.Moreover,the as-prepared CoFe2O4materials exhibiteda high specific surface area(140.6m2gÀ1)and high porosity(0.23cm3gÀ1).The fabricated CoFe2O4electrode showed typical pseudocapacitive behavior with a broad potential window(1.5V),a highspecific capacitance(142F gÀ1,2mV sÀ1)and a long cycling life(71.8%retention after1000cycles).&2013Elsevier B.V.All rights reserved.1.IntroductionWith worldwide increasing warmth in the energy storagefieldof supercapacitors,3d transition metal oxides ranging from noblemetal oxides to inexpensive metal oxides,characterized by highlyreversible capacities,long cycle performance and high powerdensity,have been extensively studied[1].Among them,RuO2could exhibit prominent performance with pseudocapacitance ashigh as720F gÀ1[2],but the expensive cost and high toxicityapparently hinder its commercial application,which made MnO2,Co3O4,Fe3O4,V2O5and NiO,especially binary system materialsCo–Ni,Fe–Mn,Co–Mn,Mn–Ni oxides environmental and econom-ical alternatives of choice for improved applicability[1].Ferrosoferric oxide(Fe3O4)and cobalt oxide(Co3O4)of spinelseries are both attractive candidates for the application in super-capacitors owning to their low-cost and environmental friendlynature,as well as excellent electrochemical capacitive behavior[3,4].Their binary compound cobalt iron oxide(CoFe2O4),as anefficient magnetic material on demand infields of electronics,photomagnetism,catalysis,has widely been studied[5].In2005,Kuo and Wu[6]had a report of CoFe2O4with a specific capacitanceof7.1F gÀ1in neutral NaCl electrolyte,which shed light on itselectrochemical properties by improving inherent structure.Herein,we employ a hard template of Al2O3derived from co-precipitating Al(NO3)3precursor solution to fabricate the porouscapacitive CoFe2O4.And the artificial porous structures are provedto largely enhance the electrochemical performance of theCoFe2O4materials.2.ExperimentalIn a typical procedure,first,2.25g Al(NO3)3Á9H2O,4.85g Fe(NO3)3Á9H2O and1.75g Co(NO3)2Á6H2O were dissolved in120mLdeionized water to form a well-mixed solution.ExcessiveNH3ÁH2O was subsequently added to the solution dropwise untila pH level of10was reached.The obtained dark brown precipita-tion was further vigorously stirred at501C for4h with a constantspeed in a water-jacketed reaction vessel using circulating ther-mostatic bath.Then,the as-prepared sample was obtained bycentrifugalfiltration and dried at701C for10h,afterwardannealed in a muffle stove at4501C under air for2h at a heatingrate of21C minÀ1.Subsequently,the product was etched in2MKOH solution at501C for24h to remove Al2O3template,after-wardfiltrated by centrifugation and washed with distilled waterseveral times until a neutral pH level,andfinally dried at701Cfor10h.For comparison,the experiment without Al(NO3)3Á9H2Oaddition was also conducted.Thefinal products with andwithout Al2O3template are named T-CoFe2O4and CoFe2O4,respectively.Contents lists available at ScienceDirectjournal

D/max-2500diffractometer equipped with monochromated Cu K α(λ¼0.15406nm)radiation.Scanning electron microscopy (SEM)images were taken using Philips XL 30and a JEOL JSM-6700F microscope.N 2adsorption –desorption measurements were performed on a Micromeritics ASAP 2020apparatus.Electrochemical examinations were carried out with a CoFe 2O 4working electrode,a Pt mesh counter electrode and a Hg/HgO (2M KOH aqueous solution)reference electrode.The working electrodes were prepared by pressing the homogenous mixture of 70wt%CoFe 2O 4active materials,15wt%acetylene black,and 15wt%poly(tetra fluoroethy-lene)(Sigma Aldrich)onto a stainless steel mesh collector.Cyclic voltammetry (CV)and cyclic stability were collected on CHI700D electrochemical workstation and land CT2001A tester,respectively.The gravimetric speci fic capacitance (C m )is calculated accord-ing to the following equation:C m ¼12vm ðΔV ÞZ V bV a I d V ð1Þwhere m ,νand (V a –V b )i.e.ΔV denote the mass of CoFe 2O 4or T-CoFe 2O 4active powders,scan rate and the potential window (1.5V),respectively.3.Results and discussionFig.1a displays the XRD patterns of T-CoFe 2O 4and CoFe 2O 4materials.All the resultant peaks can be indexed as a face-centered-cubic spinel phase.The identi fied eight diffraction peaks at 2θvalue of 30.211,35.701,37.131,43.161,54.131,57.361,62.961and 74.321correspond to the (220),(311),(222),(400),(422),(511),(440)and (533)crystal planes,respectively,which is in well agreement with the standard patterns for CoFe 2O 4(JPCDS No.22-1086).No signals of Al 2O 3phase (JCPDS No.10-0425)aredetected in the patterns [7].Moreover,neither does Al emerge in XPS nor in EDAX spectra of T-CoFe 2O 4(seen in Fig.S1and S2).All suggested the successful removal of the template.Furthermore,it is clearly seen that diffraction peaks of T-CoFe 2O 4are duller indicating T-CoFe 2O 4comprises of smaller nanoparticles than CoFe 2O 4and this inference is further con firmed by their SEM images (Fig.1b and c).The CoFe 2O 4in Fig.1b,shows basically microsized agglomerate particles with few pores and voids,and a smooth surface,whereas the T-CoFe 2O 4exhibits basically dis-persed and uniform spherical-like particles of around 25nm size with rough surface and high porosity,as can be seen in the domain of Fig.1c.Thus by etching the hard template,T-CoFe 2O 4exhibits a porous framework with smaller granular size rather than bulk.To accommodate super ficial electroactive species as much as possible,it is essential for the electrode material to enrich its inner surface area and pores so as to ease the mass transfer of electrolytes [8].The surface area and porosity of the T-CoFe 2O 4and CoFe 2O 4were further veri fied by nitrogen sorption measurements which are shown in Fig.1d.The N 2adsorption –desorption isotherms of CoFe 2O 4and T-CoFe 2O 4representative of type II and IV curves with distinct hyster-esis loops.The BET surface area of T-CoFe 2O 4is 140.6m 2g À1which is far larger than the value of 27.6m 2g À1for CoFe 2O 4.The main pore size distributes narrowly in the range of 4–8nm centered at 5.6nm and 2–4nm centered at 2.2nm for the T-CoFe 2O 4and CoFe 2O 4,respectively,(shown in the insets of in Fig.1d).Besides,average pore size and mesoporous volume of T-CoFe 2O 4are quantitatively eval-uated as 6.53nm and 0.23cm 3g À1,and the corresponding values of CoFe 2O 4are 2.2nm and 0.225cm 3g À1,respectively.High speci fic surface area and porosity is critical to enhance the electrochemical performances of electrode materials for supercapacitors [1].Thereby,improved electrochemical properties for the porous T-CoFe 2O 4,such as speci fic capacitance,high-rate capability,and longer cycling life,can be expectedaccordingly.Fig.1.XRD patterns (a)and N 2adsorption –desorption isotherms with insets of BJH pore size distribution (d)of CoFe 2O 4and T-CoFe 2O 4;SEM images of CoFe 2O 4(b)and T-CoFe 2O 4(c).L.Lv et al./Materials Letters 111(2013)35–3836The CV plots of CoFe 2O 4and T-CoFe 2O 4electrodes tested in the potential range of À1.0–0.5V were plotted in Fig.2a and b.Two obvious pseudocapacitive blocks are observed in the positive (À0.1–0.5V)and negative (À0.5–À1.0V)potential regions which contribute to most of the capacitance.While the middle intervals (À0.1–À0.5V)contribute to the minor EDL capacitance [9].Here,the observed redox couples well elucidate the pseudocapacitive properties of CoFe 2O 4electrodes.The three couples of redox peaks located at around 0.28/0.05V,0.5/0.38V,À0.75/À0.85V indicate the reversible redox processes of Co 3þ/Co 2þ,Co 4þ/Co 3þ,Fe 3þ/Fe 2þredox couples in alkaline electrolytes [4,9,10],which can be expressed as the following equations:1/3Co 3O 4þ1/3OH Àþ1/3H 2O 2CoOOH þ1/3e À(2)CoOOH þOH À2CoO 2þH 2O þe À(3)2/3Fe 3O 4þ2/3OH ÀþH 2O 22FeOOH þ2/3e À(4)Even though a series of reports have studied the capacitive properties of M Fe 2O 4(M ¼Mn,Fe,Co,Ni),CoFe 2O 4in our work may draw fresh attention as it can both act as anode and cathode electrode materials by virtue of the broad potential window area.The speci fic capacitance values of CoFe 2O 4and T-CoFe 2O 4electrodes are shown in Fig.2c,both speci fic capacitance decreases with increasing scan rate because of insuf ficient active material involved in the redox reactions under higher scan rate.The CoFe 2O 4electrode exhibits a low speci fic capacitance range of 44–13F g À1while the T-CoFe 2O 4electrode exhibits a much higher and considerable speci fic capacitance range of 142–23F g À1in the scan rate range of 2–50mV s À1.Obviously,the porous T-CoFe 2O 4has much higher electrochemical activity than the bulk CoFe 2O 4thanks to suf ficient electroactive sites for electrochemical reac-tions and easy ion diffusion pathways for electrolyte ions transfer process.Long cycle life is a crucial parameter for electrode materials used for supercapacitors.The cyclic performances of CoFe 2O 4and T-CoFe 2O 4electrodes are shown in Fig.2d.The CoFe 2O 4electrodeshowed a capacitance ′s decay in the first 200cycles,then gradually went up with the increasing cycle numbers and finally a retention rate of 68.7%was obtained.The speci fic capacitance of T-CoFe 2O 4,which is nearly three times of CoFe 2O 4,slightly decreased before 200cycles and remained almost stable in the subsequent cycles.A retention rate of 71.8%was obtained after 1000cycles for the T-CoFe 2O 4electrode.Here,the decline in the speci fic capacitance with cycle number may be ascribable to the loss of active material caused by the dissolution and/or detach-ment during early cycle number [11].Further work on searching the most appropriate ratio of template to improve the cycling behavior is currently under progress.4.ConclusionsIn summary,the mesoporous CoFe 2O 4materials for super-capacitors have been successfully synthesized with assistance of co-precipitating Al 2O 3template.High BET speci fic surface and porosity of 140.6m 2g À1and 0.23cm 3g À1were obtained which facilitate the Faradaic pseudocapacitive performance by virtue of suf ficient electroactive sites and easy ions pathways.The unique mesoporous CoFe 2O 4electrode delivered a wide potential window of 1.5V and a high speci fic capacitance of 142F g À1at 2mV s À1,which can be expected to take important roles in both anode and cathode materials for supercapacitors.AcknowledgmentsWe gratefully acknowledge the financial support of this research by National Basic Research Program of China

Organic Letters投稿模板说明书

Organic Letters投稿模板说明书

Instructions for Using the Organic Letters Manuscript TemplateWord 2010 for WindowsThe Organic Letters manuscript template is a guide to be used to prepare manuscripts for submission to Organic Letters. There are a number of paragraph styles available for use with this template to identify the different parts of your manuscript, i.e., Title, Author Names, Abstract, etc. In Microsoft Word, the name of the current paragraph style is displayed in the Styles section of the home tab. Use the styles provided in the template for each corresponding section of your paper. The template is designed to closely approximate a composed manuscript. A manuscript may not exceed 2200 words, including abstract, main text, and titles/footnotes of approximately five to eight graphics. Additional graphics will require areduced word count. To calculate the word count, select all text from the abstract through the end of the main text (excluding title, authors, affiliations, and content after main text) and view the word processor word count data NOTE: references are NOT included in the word count.. For best approximation, do not manipulate elements of the template such as font size, margins, spacing,etc. to suit your word processed draft. Formatting in the Organic Letters journal style will occur as part of the editorial production process.Authors should refer to the documentation for their individual word processor or graphics package for answers to questions directly related to those programs.Downloading the template1.From the Organic Letters Information for Authors page, click on the manuscripttemplate that corresponds to the version of word-processing software you will be using to prepare your manuscript.2.Save the template in the Templates folder. With the template open in Word, click Filethen Save As. Scroll to the top of the folder list, Click Microsoft Word, then clickTemplates. In the Save as type drop down list, select Word Template, then click Save.This places the template in the proper folder so it will be listed as an available template for manuscript preparation.Working with the templateThere are several ways to use this template to generate your final manuscript to be submitted for publication. Two of the most straightforward are to (a) type your manuscript directly in the template or (b) attach the template to a working document. Instructions are given below for each of these methods as well as general instructions for all methods. Be sure to frequently check the Organic Letters Information for Authors page to ensure that you are using the most recent version of the template.For best results, template method A is recommended.A.Typing directly into the template1.Open the saved OL template and create your manuscript directly in the template bychoosing File, New. Click My Templates to locate the OL template. NOTE: If it does not appear, open the template file from the location where you saved it and resave it as aDocument Template using the same file name. This should make it so that it does appear on the My Templates tab in the New dialog box.2.Select the OL template and make sure the option Create New: Document (not Template)is selected. Click OK. You will see a file containing sample text sections with tips forusing the template and guidelines for what each section contains. This text is formattedwith the paragraph style appropriate for the section. In addition, a Styles toolbar can bedisplayed listing the Word Styles available in the template. The Styles toolbar can beopened from the Styles menu on the ribbon or by the shortcut Alt+Ctrl+Shift+S. Whenyou use the template to create a document, the new document will be a document copy(.docx) of the template containing your manuscript text, and the original template file will remain unchanged.3.Select (highlight) the text of the template that you want to replace and begin typing yourmanuscript (i.e., select the Title section for typing in your title), ensuring that you haveselected text from the appropriate section (i.e., the Author Names section for typing inyour author names).B.Attaching the template to a documentIf you have prepared your document in a file not using the template, you can attach the template to your working document and apply the Word style tags. If attaching the template to your document, it is helpful to print a copy of the template first so that you can identify which Word style should be applied to the different sections of your manuscript (File, New, My Templates and select the OL template).1.Open your manuscript file.2.Select File on the toolbar and then Options. NOTE: There are several ways to importtemplates/styles into working documents within Word. See the "templates" section ofMicrosoft Word Help for further instructions.3.Choose Add-Ins in the Word Options dialog box.4.Select Templates from the Manage drop-down list, then click Go.5.Click the Attach button and choose the appropriate template, then select Open.6.Click Automatically update document styles, then clikc OK. This will return you to theworking document. The OL template styles will be available for this manuscript.7. A popup Styles toolbar has been generated that will display the different Word styles foreasier use. If you do not see this toolbar, do (Alt+Ctrl+Shift+S), and it should appear.You can close this at any time and reopen it when needed.8.Attaching the OL template sytles does not automatically change the page layout to matchthe template dimensions; you must make the following adjustments for the best fit. Under Page Layout, select the Margins drop down list. Select Custom Margins tab, type in the following dimensions: Top 0.5”, Bottom 0.5”, Left0.76”, Right 0.76”, Gutter 0”. On the Paper Size drop-down select More Paper Sizes,in Paper tab set size Letter, Width 8.5”, Height 11”, then on the Layout tab set the Header 0.5”, and Footer 0.5”.NOTE: Page layout settings other than those prescribed here will not give accurate layout estimates.9.Place the cursor in the title section of your document. Using the Word Style menu on theformatting toolbar, select Word Style “BA_Titl e”. This will apply the Word Style to the title.Do this for the author names and addresses using the appropriate style.10.Insert TOC/Abstract graphic (sized at desired publication size).11.Place the cursor in the abstract section of your document and apply the Word Style“BD_Abstract”.12.After the last word of the abstract, enter a continuous page break (Page Layout, Breaks,select Continuous from Breaks drop- down) then change the page format for the rest of the manuscript to two-column text. Click on the Columns drop-down from the Page Setupsection in Page Layout and select More Columns. Make the following changes in thiswindow: Number of Columns 2, Width 3.33”, Spacing 0.32”. Click OK. Assign theappropriate Word Styles to the remaining paragraphs/text of the manuscript.13.Insert figures, schemes, and tables by creating a blank line (style Normal) where you wanteach to appear, making sure the image is sized appropriately for desired reproduction in publication.Additional Guidelines (see Organic Letters Author Guidelines for complete details)1.Include a graphical entry for the Table of Contents (TOC) that, in conjunction with themanuscript title, should give the reader a representative idea of one of the following: akey structure, reaction, equation, concept, or theorem, etc., or an ingeniousrepresentation, thereof, that is discussed in the manuscript. Insert this graphic, atpublication size, above the abstract text on the first page of the template.2.Submit a concise, self-contained, one-paragraph abstract (75 words or less).Space for this is provided on the first page of the template.e paragraph returns to end headings and paragraphs only. Do not use paragraphreturns to break lines. Use a spell checker to detect any typos and eliminate any spacesbefore punctuation.4.Pay particular attention to the format of the references to ensure that they comply withjournal style. Authors are responsible for the accuracy of the references.5.Present tabular material by using the table-formatting feature in your word-processingpackage. Enter each data element in its own cell. Apply template table styles to tabletitles, footnotes, and table body text.6.Ensure all characters are correctly represented throughout the manuscript: for example, 1(one) and l (ell), 0 (zero) and O (oh). Use symbol font for all Greek letters and mathsymbols. Use only characters in your file that came with the character sets in your wordprocessor.Working with graphics in the templateTo insert a graphic within the text or as a figure, scheme, or table, create a new line (Wordstyle “Normal”) and insert the graphic where desired.Size and place the graphics at the size they should be in the journal. For best results, most artwork should be sized to fit in a single journal column. NOTE: If your artwork is larger than the width of a column, Word may reduce the size so that it fits within the column. This will alter the resolution of your graphic and may make it unacceptable for publication.For double column artwork, enter a continuous page break, change number of columns from 2 to 1, place the artwork, then insert another continuous page break and configure two columns with previous settings.If your artwork does not appear where you placed it and is floating over text, select the piece of artwork by clicking on it. Under Picture Tools, select Picture or Object and then select the Position tab. Make sure the Float over text box is NOT selected. If it is, deselect it and select OK. This should make your artwork appear where you originally placed it.ChemDraw directionsFollow the drawing settings in the ACS-1996 Style Sheet for preparing your artwork. It is best to copy the actual artwork and paste it into Word rather than saving it as a file and inserting the file. In addition, for versions later than 2.1.3, in the ChemDraw Preferences (File, Preferences), ensure that the Optimize for High-Resolution non-Postscript Printing, Include ChemDraw LaserPrep, and Include PostScript Preferences are ON. Use of ChemDraw versions 2.1.3 or below and any version of ChemDraw Plus is not encouraged, as they are not compatible with the process that generates the PDF file for your manuscript. If it is absolutely necessary to use one of these older versions of ChemDraw, deselect Include PostScript Atom Labels (File, Preferences). This will prevent incompatible PostScript information from being embedded in the structure. NOTE: this may result in structures of inferior quality; thus, the use of an updated version of ChemDraw is strongly encouraged.Saving your manuscript in the templateWhen you are finished and are ready to save your document, if necessary, delete all sections from the template that are not needed, including the first page of instructions. Assign the file a name that will identify your manuscript, one that is different than that of the template. Save the file with the graphics in place. In Microsoft Word, click Save As (File menu) and save it as a “docume nt” file (.docx).NOTE: To use the template with Microsoft Word 2007 (PC version) and Microsoft Word 2008 (Macintosh version), Save your Word files in the compatibility format (Word 97-2003) using the “Save As” option.Checking your manuscript for completenessReview a printout of the manuscript (from a 600 dpi or higher laser printer) to ensure that all parts of the manuscript are present and clearly legible.Submitting your manuscriptFollow the Author Guidelines link from the Organic Letters home page for the latest instructions on how to proceed with the submission of your manuscript. If submitting electronically, your manuscript will be converted to a PDF file. This file is used strictly for peer review. The length of the file when converted to the PDF version may change. Additional formatting changes may occur in prodouction. In addition, the appearance of footnote numbers does not need to be changed to match the journal style.Additional resourcesAuthors should refer to the User's Guides for their individual word processor and graphics programs for more specific instructions on how to use these packages. In addition, most software manufacturers maintain on-line help resources. Two good sources of additional information are the Microsoft Web site (/) and the ChemDraw Web site (/software/ChemDraw/).Appendix: ReferencesGiven below are the recommended formats to be used for the various reference types.

以下是Materials Letters的作者指南,我觉得它已经非常简明的说清楚整个投稿过程需要注意的东西2009年影响因子:1.94Guide for Authors Materials LettersMaterials Letters is dedicated to publishing novel, cutting edge reports of broad interest to the materials community. The journal provides a forum for materials scientists and engineers, physicists, and chemists to rapidly communicate on the most important topics in the field in materials. We are primarily interested in those contributions which bring new insights, and papers will be selected on the basis of the importance of the new knowledge they provide.Contributions include a variety of topics such as:• Materials- Metals and alloys, amorphous solids, ceramics, composites, nanocrystals, polymers, semiconductors.• Applications - Structural, opto-electronic, magnetic, medical, MEMS, sensors, smart.• Characterization- Analytical, microscopy, scanning probes, nanoscopic, optical, electrical, acoustic, spectroscopic, diffraction.• Novel Materials- Micro and nanostructures (nanowires, nanotubes, nanoparticles), nanocomposites, thin films, superlattices, quantum dots.• Processing - Thin film processing, sol-gel processing, mechanical processing, assembly, and nanocrystalline processing leading to unique materials.• Properties - Mechanical, magnetic, optical, electrical, ferroelectric, thermal, interfacial, transport, thermodynamic.• Synthesis- Quenching, solid state, solidification, solution synthesis, vapor deposition, and high pressure, explosive processes leading to unique materials. The following topics are inappropriate for publication:Building materials - aggregate, asphalt, cement, concrete, plasterCatalytic materialsCorrosion and oxidation phenomena and protectionLiquid crystalsMetallurgical ProcessesNatural raw materials – clays, minerals, rocksOxide glasses and glass ceramicsRecycled materialsRefractoriesSingle crystal growthTheoryWearTypes of Contribution:Letters are intended as brief reports of significant, original and timely research results on the science, applications and processing of materials which warrant rapid publication. In considering a manuscript for publication, particular attention will be given to the originality of the research, the desirability of speedy publication, the clarity of the presentation and the validity of the conclusions. There is a strict four-page limit to printed articles. Manuscripts must not exceed 2000 words plus three figures and one table. The maximum number of figures is strictly limited to five. If the maximum of 5 figures is used, then the total number of words must be reduced to 1600. If more than 5 figures are used, the manuscript will be rejected. The manuscript submitted for review should not exceed 8 pages (including title, abstract, references, figures, tables and figure captions).Contact Details:Authors should submit their article via the online submission system. Authors will be asked to choose the Editor whose subject area is most closely aligned to the subject of their article. Each Editor's specialties are given below. To expedite the review process, authors will also be prompted to nominate 3 potential referees, who are not at the same institute, to serve as potential referees. Contact details are helpful.Principal EditorsProf. J. Hojo - Nano-composites, Composites, Sol-gel preparationProf. T.G. Nieh - Metallic Alloys, Ceramics, Composites, High Temperature Materials, Mechanical Behavior, Material ProcessingProf. L.S. Shvindlerman - Nano-Crystalline Metals, Thermodynamics, Kinetics, Interfaces and Surfaces.Prof. A.F.W. Willoughby - Semiconductor/Electronic Materials, PolymersOnline Submission:Authors must submit their articles using the secure online submission system at .To facilitate rapid publication, it is essential to precisely follow these instructions. Failure to do so can result in a delay or rejection of the manuscript for publication. To ensure a timely review you will be required to answer the following questions before your paper will be considered for review.• Has your paper, or par t of your paper, been published before, or is it currently submitted for review to another journal?Yes / No(If yes, then do not submit your paper to Materials Letters.)• Is the total number of words less than 2000?Yes / No(If greater than 2000, please reduce the number of words.)• Is the number of figures greater than 5?Yes / No(If yes, then the paper will automatically be rejected.)• Are the x-ray diffraction patterns indexed?Yes / No(see 4.10) (If your x-ray patterns are not indexed, the paper will be rejected for publication.) [?奇怪]• Do the micrographs have professional quality scale markers?Yes / No(Please replace the black bar on SEM & TEM micrographs with a professional quality scale marker. See 4.9)Ethics in PublishingFor information on Ethics in Publishing and Ethical guidelines for journal publication see and .Policy and ethicsThe work described in your article must have been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans; EC Directive 86/609/EEC for animal experiments; Uniform Requirements for manuscripts submitted to Biomedical journals. This must be stated at an appropriate point in the article.Conflict of interestAll authors are requested to disclose any actual or potential conflict of interest including any financial, personal or other relationships with other people or organizations within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work. See also . Submission declarationpreviously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.CopyrightUpon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (for more information on this and copyright see ). Acceptance of the agreement will ensure the widest possible dissemination of information. An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.Subscribers may reproduce tables of contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of the Publisher is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations (please consult ). If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. Elsevier has preprinted forms for use by authors in these cases: please consult .Retained author rightsAs an author you (or your employer or institution) retain certain rights; for details you are referred to: .Role of the funding sourceYou are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the paper for publication. If the funding source(s) had no such involvement then this should be stated. Please see .Funding body agreements and policiesElsevier has established agreements and developed policies to allow authors whose articles appear in journals published by Elsevier, to comply with potential manuscript archiving requirements as specified as conditions of their grant awards. To learn more about existing agreements and policies please visit .Language and language servicesPlease write your text in good English (American or British usage is accepted, but not a mixture of these). Authors who require information about language editing and copyediting services pre- and post-submission please visit or our customer support site at for more information.SubmissionSubmission to this journal proceeds totally online and you will be guided stepwise through the creation and uploading of your files. The system automatically converts source files to a single PDF the article, which is used in the peer-review process. Please note that even though manuscript source files are converted to PDF files at submission for the review process, these source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by e-mail removing the need for a paper trail.RefereesPlease submit, with the manuscript, the names, addresses and e-mail addresses of 3 potential referees. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.Use of wordprocessing softwareIt is important that the saved in the native format of the wordprocessor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the wordprocessor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. Do not embed "graphically designed" equations or tables, but prepare these using the wordprocessor's facility. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: ). Do not import the figures into the text , instead, indicate their approximate locations directly in the electronic text and on the manuscript. See also the section on Electronic illustrations.To avoid unnecessary errors you are strongly advised to use the "spell-check" and "grammar-check" functions of your wordprocessor.Follow this order when submitting manuscripts: Title, Authors, Affiliations, Abstract, Keywords, Main text, Acknowledgements, Appendix, References, Figure Captions and then Tables. For submission via the website you are requested to import low-resolution images into the article at the approximate location you wish them to appear. Thus the PDF which is created for refereeing purposes will contain all necessary information. In addition you will be asked to separately upload high quality images. Collate acknowledgements in a separate section at the end of the article and do not include them on the title page, as a footnote to the title or otherwise.Text LayoutUse double spacing and wide (3 cm) margins. (Avoid full justification, i.e., do not use a constant right-hand margin.) Ensure that each new paragraph is clearly indicated. Present tables, figures and figure legends at the point they will appear in the manuscript. If possible, consult a recent issue of the journal to become familiar with layout and conventions. Number all pages consecutively, use 12 or 10 pt font size and standard fonts.Subdivision - numbered sectionsDivide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to "the text". Any subsection may be given a brief heading. Each heading should appear on its own separate line. IntroductionState the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.Material and methodsProvide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.Theory/calculationA Theory section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis. ResultsResults should be clear and concise.DiscussionThis should explore the significance of the results of the work, not repeat them.A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.ConclusionsThe main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.Essential title page information• Title.Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.• Author names and affiliations.Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.• Corresponding author.Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.• Present/permanent address.If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.Abstract:A self-contained abstract of 100 to 200 words, outlining in a single paragraph the aims, scope and conclusions of the paper must be supplied. Do not list the analytical equipment (e.g. SEM, XRD, TEM) used unless it is critical to the meaning. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separate from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, they must be cited in full, without reference to the reference list. Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.KeywordsImmediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, "and", "of"). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.AcknowledgementsCollate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).Nomenclature and unitsFollow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI. You are urged to consult IUGS: Nomenclature for geological time scales/rock names: for further information.Math formulaePresent simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).ArtworkElectronic artworkGeneral points• Make sure you use uniform lettering and sizing of your original artwork.• Save text in illustrations as "graphics" or enclose the font.• Only use the following fonts in your illustrations: Arial, Courier, Times, Symbol. • Number the illust rations according to their sequence in the text.• Use a logical naming convention for your artwork files.• Provide captions to illustrations separately.• Produce images near to the desired size of the printed version.• Submit each figure as a separ ate file.A detailed guide on electronic artwork is available on our website:You are urged to visit this site; some excerpts from the detailedFormatsRegardless of the application used, when your electronic artwork is finalised, please "save as" or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):EPS: Vector drawings. Embed the font or save the text as "graphics".TIFF: color or grayscale photographs (halftones): always use a minimum of 300 dpi.TIFF: Bitmapped line drawings: use a minimum of 1000 dpi.TIFF: Combinations bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is required.DOC, XLS or PPT: If your electronic artwork is created in any of these Microsoft Office applications please supply "as is".Please do not:• Supply embedded graphics in your wordprocessor (spreadsheet, presentation) document;• Supply files that are optimised for screen use (like GIF, BMP, PICT, WPG); the resolution is too low;• Supply files that are too low in resolution;• Submit g raphics that are disproportionately large for the content.Color artworkPlease make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color in print or on the Web only. For further information on the preparation of electronic artwork, please see .Please note: Because of technical complications which can arise by converting color figures to "gray scale" (for the printed version should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.Figure captionsEnsure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used. TablesPlace footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.ReferencesCitation in textPlease ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either "Unpublished results" or "Personal communication" Citation of a reference as "in press" implies that the item has been accepted for publication.Web referencesAs a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.References in a special issuePlease ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue. Reference management softwareThis journal has standard templates available in key reference management packages EndNote () and Reference Manager (). Using plug-ins to wordprocessing packages, authors only need to select the appropriate journal template when preparing their article and the list of references and citations to these will be formatted according to the journal style which is described below. Reference styleText: Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given.List: Number the references (numbers in square brackets) in the list in the order in which they appear in the text.Examples:Reference to a journal publication:[1] Van der Geer J, Hanraads JAJ, Lupton RA.

The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. The correct format for citing a DOI is shown as follows (example taken from a document in the journal Physics Letters B): doi:10.1016/j.physletb.2003.10.071When you use the DOI to create URL hyperlinks to documents on the web, they are guaranteed never to change.ProofsOne set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 (or higher) available free from . Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site: .If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (includingreplies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately. Therefore, it is important to ensure that all of your corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received.OffprintsThe corresponding author, at no cost, will be provided with a PDF the article via e-mail or, alternatively, 25 free paper offprints. If the corresponding author opts for paper offprints, this preference must be indicated via the offprint order form which is sent once the article is accepted for publication. Additional paper offprints can also be ordered via this form for an extra charge. The PDF a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use. Keyword List(被省略)。

The system automatically converts source files to a single PDF file of the article, which is used in the peer-review process. Please note that even though manuscript source files are converted to PDF files at submission for the review process, these source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by e-mail removing the need for a paper trail.RefereesPlease submit, with the manuscript, the names, addresses and e-mail addresses of 3 potential referees. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.Use of wordprocessing softwareIt is important that the file be saved in the native format of the wordprocessor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the wordprocessor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. Do not embed "graphically designed" equations or tables, but prepare these using the wordprocessor's facility. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronictext should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: /guidepublication). Do not import the figures into the text file but, instead, indicate their approximate locations directly in the electronic text and on the manuscript. See also the section on Electronic illustrations.To avoid unnecessary errors you are strongly advised to use the "spell-check" and "grammar-check" functions of your wordprocessor.Article structureFollow this order when submitting manuscripts: Title, Authors, Affiliations, Abstract, Keywords, Main text, Acknowledgements, Appendix, References, Figure Captions and then Tables. For submission via the website you are requested to import low-resolution images into the article at the approximate location you wish them to appear. Thus the PDF which is created for refereeing purposes will contain all necessary information. In addition you will be asked to separately upload high quality images. Collate acknowledgements in a separate section at the end of the article and do not include them on the title page, as a footnote to the title or otherwise.Text LayoutUse double spacing and wide (3 cm) margins. (Avoid full justification, i.e., do not use a constant right-hand margin.) Ensure that each new paragraph is clearly indicated. Present tables, figures and figure legends at the point they will appear in the manuscript. If possible, consult a recent issue of the journal to become familiar with layout and conventions. Number all pages consecutively, use 12 or 10 pt font size and standard fonts.Subdivision - numbered sectionsDivide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to "the text". Any subsection may be given a brief heading. Each heading should appear on its own separate line. IntroductionState the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.Material and methodsProvide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications shouldbe described.Theory/calculationA Theory section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis. ResultsResults should be clear and concise.DiscussionThis should explore the significance of the results of the work, not repeat them.A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.ConclusionsThe main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.Essential title page information• Title.Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.• Author names and affiliations.Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.• Corresponding author.Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.• Present/permanent address.If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.Abstract:A self-contained abstract of 100 to 200 words, outlining in a single paragraph the aims, scope and conclusions of the paper must be supplied. Do not list the analytical equipment (e.g. SEM, XRD, TEM) used unless it is critical to themeaning. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separate from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, they must be cited in full, without reference to the reference list. Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.KeywordsImmediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, "and", "of"). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.AcknowledgementsCollate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).Nomenclature and unitsFollow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI. You are urged to consult IUGS: Nomenclature for geological time scales/rock names: / for further information.Math formulaePresent simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).ArtworkElectronic artworkGeneral points• Make sure you use uniform lettering and sizing of your original artwork.• Save text in illustrations as "graphics" or enclose the font.• Only use the following fonts in your illustrations: Arial, Courier, Ti mes, Symbol.• Number the illustrations according to their sequence in the text.• Use a logical naming convention for your artwork files.• Provide captions to illustrations separately.• Produce images near to the desired size of the printed version.• Submit each figure as a separate file.A detailed guide on electronic artwork is available on our website:/artworkinstructionsYou are urged to visit this site; some excerpts from the detailed information are given here.FormatsRegardless of the application used, when your electronic artwork is finalised, please "save as" or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):EPS: Vector drawings.

propertiesMixed surfactant solution,containing cetyltrimethyl ammonium bromide (CTAB)and sodium dodecylbenzyl sulfonate (SDBS),is used to prepare polyaniline (PANI)with soft 1D structure and high electrical conductivity.The mixed surfactants in the reaction play double roles of soft templates and dispersion reagents.The in fluence of CTAB –SDBS ratio on the morphology and conductive property of PANI is investigated.Through varying the proportion of surfactants,uniformly branched nano fibers with higher aspect ratio and good dispersion are obtained,which possess the highest conductivity (0.102S·cm −1).Moreover,FT-IR spectra are measured to explain the change of structure and conductivity under assistance of mixed surfactants.As a result,the mixed surfactants have signi ficant effect on the electron density of whole structure as well as the PANI molecular orientation.©2011Elsevier B.V.All rights reserved.1.IntroductionAmong conducting polymers,polyaniline (PANI)has been exten-sively investigated because of its easy polymerization,chemical stability,environmental friendliness and relatively high conductivity.In recent years,one-dimensional (1D)PANI nanomaterials,such as nano-fiber/-wire/-rod/-tube,have aroused considerable interest because of their delicate structures and enhanced performance.Generally,surfactant-assisted growth is one of the most effective ways to produce 1D PANI nanostructures among various chemical methods [1,2].In comparison to single surfactant reaction,mixed surfactant systems have attracted more and more attention due to their unique structure tailoring effects as templates [3].Zhao and Qi have indicated that controlled morphology of semiconductors could be easily achieved in cationic/anionic mixed-surfactants [4].Dendritic silver crystals could be obtained in the mixture of CTAB –SDS or CTAB –SDBS [5,6].As proved by these evidences,the synergism of anionic sur-factant and cationic surfactant is important to the formation of well-controlled morphology.However,there are few literatures reported about the mixed surfactants in aniline polymerization reaction.Moreover,the evolution of morphology as well as electrical conductivity of PANI that mediated by varying the ratio of mixed surfactants system has not been investigated so far.In the previous works,conductive polymers with morphology of nanospheres and nano fibers were synthesized via a surfactant-assisted polymerization method [7,8].Herein,the route of mixed surfactants (CTAB –SDBS)assisted growth is introduced to prepare PANI nano fiber with high electrical conductivity.Since the polymer-ization process of aniline is conducted in mixed surfactants,the morphology and physicochemical properties are altered by varying the ratios of CTAB to bined with FT-IR analysis of PANI chains,the correlation between structure and electrical conductivity is illustrated.2.Materials and methods 2.1.Synthesis of PANI0.91mL aniline was dissolved in 100mL doubly distilled water,and then [CTAB]:[SDBS]as 2:1(6mM:3mM)was added under vigorous stirring for 30min in an ice –water bath.10mL of pre-cooled ammonium persulfate (APS)aqueous solution was added to initiate the oxidative polymerization.The reactant solution was stirred for 12h in an ice –water bath.The molar ratio of aniline to APS ([An]/[APS])was retained at 1:1.The precipitate was centrifuged and washed to remove the remaining surfactants and organic residuals.Finally,the product was dried in a vacuum chamber,labeling as S4.In this way,a series of PANI samples were obtained from different molar ratios of [CTAB]:[SDBS](0:1,1:2,1:1,4:1and 1:0)by maintaining the total surfactant concentration (9mM),which were labeled as S1,S2,S3,S5,and S6,respectively.Materials Letters

t2.2.CharacterizationSEM measurement was carried out at an S-4800(Hitachi,Japan)to study the morphology.For conductivity measurements,the polymer samples were pressed into a10mm diameter disk and analyzed using a four-probe conductivity instruments(SDY-4,Guangzhou Semicon-ductor Material Institute,China).The resistivity of the samples was measured atfive different positions.The average of5readings was used for conductivity calculations.The FT-IR spectra were tested on Nicolet Avatar360FT-IR Spectrometric Analyzer with KBr pellets.3.Results and discussionTypical morphologies of PANI samples prepared in surfactant systems with different ratios of CTAB to SDBS are recorded and com-pared in Fig.1.As shown in Fig.1a,irregular PANIfibers are obtained in the medium of pure SDBS surfactant because uneven charges are formed on the surface of materials using this kind of anionic micelle [9].While in pure CTAB medium,uniformly curlyfibrillar morphology can be observed(Fig.1f).Since the mixed micelle of CTAB and SDBS is beneficial to the formation of worm-like structure[4],short worm-like structure with some aggregations appeared in sample S2(Fig.1b). With increasing the proportion of CTAB,the aspect ratio of1D struc-ture increased and relatively straightfibrillar morphology was formed by the stretch and intersection offibers(Fig.1c and d).Also,the aggregation was gradually alleviated.If further increasing CTAB in mixed surfactants,the curving and serious aggregations were observed(Fig.1e).It can be concluded that the disproportionate mixtures of CTAB and SDBS are inclined to generate aggregations because of the strong electrostatic interactions between cationic and anionic surfactants.The charge of mixed micelle can be balanced in CTAB–SDBS system of molar ratio as2:1,which is favorable for the formation of longer PANIfibers with good dispersion and many branches.On the other hand,the introduction of mixed surfactants has some influence on the surface of PANI products.The smooth surface of PANI is obtained in each single-component surfactant, while coarse surface of PANI with the decoration of knobbles are achieved in mixed surfactants.The mixing ratio of proportionate CTAB–SDBS(2:1)is beneficial to form branches through the oriented growth of knobbles on PANIfibers.The reason may be the complicated electrostatic interactions of aniline monomer with mixed micelle,formed by cationic and anionic surfactants.Fig.2shows the electrical property of PANI from different ratios of CTAB to SDBS.The conductivity of products prepared in any single-component surfactant is relatively low,for instance,5.3×10−3S·cm−1 for S1(only SDBS)and1.9×10−3S·cm−1for S6(only CTAB),which are of the same order of magnitude as compared to the value reported by literatures for the PANI from micellar templates[10,11].Inmixed Fig.1.SEM images of PANI samples prepared from different molar ratios of[CTAB]to[SDBS].(a)S1(0:1),(b)S2(1:2),(c)S3(1:1),(d)S4(2:1),(e)S5(4:1)and(f)S6(1:0). 3602 D.Zhou et al./Materials Letters65(2011)3601–3604surfactant systems,the conductivity of PANI dramatically increases when the fraction of CTAB increases from 0%to 67%and then sharply decreases from 67%to 100%.The highest value of 0.102S·cm −1is obtained in sample S4(2:1of [CTAB]:[SDBS]),almost two orders of magnitude higher than that from single surfactant.The electrical conductivity could be affected by the morphology of π-conjugation polymers from respects of density of electrons and arrangement of PANI molecular chains [12].Relatively lower conductivity is observed in S1and S6with smooth surface from single surfactants.In contrast,all products from mixed surfactants possess higher conductivity although the aggregation is serious and the length is shorter except S4.The improvement of conductivity may be attributed to high density of electrons as a result of dense knobbles throughout PANI chains.The highest electrical conductivity is achieved in 2:1of CTAB –SDBS system (S4),which generated uni-formly branched fibers with higher aspect ratio and good dispersion.The electrons are free to move throughout the length of nano fibers and further extend to the branch regions,leading to the increased delocalization of charge,which bene fits the improvement of conduc-tivity.It can be inferred that the mixed surfactants have special effect on the electron density of whole structure as well as the PANI molecular orientation.Therefore,the optimizing of morphology as well as electrical conductivity of PANI can be achieved in a preferable CTAB –SDBS ratio.Fig.3shows the FT-IR absorption spectra of PANI samples from different ratio of CTAB to SDBS.The bands at 1632and 1488cm −1areattributed to C=N and C=C stretching modes for quinonoid (Q)and benzenoid (B)rings,respectively.The bands at 1308and 1240cm −1are attributable to C ―N stretching for benzenoid ring of PANI.The peak at 1116cm −1can be assigned to the in-plane bending vibration of C ―H of aromatic rings (mode of N=Q=N,Q=N ―B and B ―NH ―B).The band at 798cm −1is associated with out-of-plane C ―H bending mode of aromatic rings.From the comparative analysis of samples,varying ratios of surfactants has little in fluence on the Q-or B-type skeleton structure of PANI.The prominent change of the spectra is the C=N stretching of Q-type PANI between single-surfactant and mixed-surfactants,showing a red shift to 1566cm −1by broadening the absorption band [9].The appearance of multiple frequencies in samples from mixed-surfactants suggests the improv-ing conjugation of C=N with C=C in polyaniline chain [13].In the presence of CTAB and SDBS,the polymerization of aniline monomer is limited in the porous channel of mixed micelles,which causes the ordered arrangement of molecular chain.Thus the spread of electron cloud of quinone-imine ring occurs in the whole PANI chain through the delocalization of charge,resulting in the enhanced conjugation effect and the reduced surface charge density [14].This trend is similar with the previous report that samples with higher electrical conductivity show shift to low vibration frequency [15].4.ConclusionIn summary,the CTAB –SDBS mixed surfactants play double roles of soft templates besides dispersion reagents in the synthesis of PANI nano fibers.The mixed micelle provides signi ficant control over the nucleation and arrangement of PANI molecular chains in the polymerization process.Uniformly branched fibers with higher aspect ratio and good dispersion are obtained by setting the molar ratio of CTAB to SDBS as 2:1.The highest value of 0.102S·cm −1is achieved in this proportion,almost two orders of magnitude higher than that from single surfactant (0.0019S·cm −1for CTAB and 0.0053S·cm −1for SDBS).The improved electrical conductivity of 1D PANI materials would extend the potential applications in microelectronic devices,catalysts,and sensors.AcknowledgmentD.Z.and Y.L.contributed equally to this research.We gratefully acknowledge financial support from the National Natural Science Foundation of China (21001037),the Specialized

See 4.9)Ethics in PublishingFor information on Ethics in Publishing and Ethical guidelines for journal publication see /publishingethics and /ethicalguidelines.Policy and ethicsThe work described in your article must have been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans /e/policy/b3.htm; EC Directive 86/609/EEC for animal experimentshttp://ec.europa.eu/environment/chemicals/lab_animals/legislation_en.htm; Uniform Requirements for manuscripts submitted to Biomedical journals . This must be stated at an appropriate point in the article.Conflict of interestAll authors are requested to disclose any actual or potential conflict of interest including any financial, personal or other relationships with other people or organizations within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work. See also /conflictsofinterest.Submission declarationSubmission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.CopyrightUpon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (for more information on this and copyright see /copyright). Acceptance of the agreement will ensure the widest possible dissemination of information. An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.Subscribers may reproduce tables of contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of t he Publisher is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations (please consult /permissions). If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. Elsevier has preprinted forms for use by authors in these cases: please consult /permissions.Retained author rightsAs an author you (or your employer or institution) retain certain rights; for details you are referred to: /authorsrights.Role of the funding sourceYou are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the paper for publication. If the funding source(s) had no such involvement then this should be stated. Please see /funding.Funding body agreements and policiesElsevier has established agreements and developed policies to allow authors whose articles appear in journals published by Elsevier, to comply with potential manuscript archiving requirements as specified as conditions of their grant awards. To learn more about existing agreements and policies please visit /fundingbodies.Language and language servicesPlease write your text in good English (American or British usage is accepted, but not a mixture of these). Authors who require information about language editing and copyediting services pre- and post-submission please visit /languageediting or our customer support site at for more information.SubmissionSubmission to this journal proceeds totally online and you will be guided stepwise through the creation and uploading of your files. The system automatically converts source files to a single PDF file of the article, which is used in the peer-review process. Please note that even though manuscript source files are converted to PDF files at submission for the review process, these source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by e-mail removing the need for a paper trail.RefereesPlease submit, with the manuscript, the names, addresses and e-mail addresses of 3 potential referees. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.Use of wordprocessing softwareIt is important that the file be saved in the native format of the wordprocessor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the wordprocessor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. Do not embed "graphically designed" equations or tables, but prepare these using the wordprocessor's facility. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronictext should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: /guidepublication). Do not import the figures into the text file but, instead, indicate their approximate locations directly in the electronic text and on the manuscript. See also the section on Electronic illustrations.To avoid unnecessary errors you are strongly advised to use the "spell-check" and "grammar-check" functions of your wordprocessor.Article structureFollow this order when submitting manuscripts: Title, Authors, Affiliations, Abstract, Keywords, Main text, Acknowledgements, Appendix, References, Figure Captions and then Tables. For submission via the website you are requested to import low-resolution images into the article at the approximate location you wish them to appear. Thus the PDF which is created for refereeing purposes will contain all necessary information. In addition you will be asked to separately upload high quality images. Collate acknowledgements in a separate section at the end of the article and do not include them on the title page, as a footnote to the title or otherwise.Text LayoutUse double spacing and wide (3 cm) margins. (Avoid full justification, i.e., do not use a constant right-hand margin.) Ensure that each new paragraph is clearly indicated. Present tables, figures and figure legends at the point they will appear in the manuscript. If possible, consult a recent issue of the journal to become familiar with layout and conventions. Number all pages consecutively, use 12 or 10 pt font size and standard fonts.Subdivision - numbered sectionsDivide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to "the text". Any subsection may be given a brief heading. Each heading should appear on its own separate line. IntroductionState the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.Material and methodsProvide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications shouldbe described.Theory/calculationA Theory section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis. ResultsResults should be clear and concise.DiscussionThis should explore the significance of the results of the work, not repeat them.A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.ConclusionsThe main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.Essential title page information• Title.Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.• Author names and affiliations.Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.• Corresponding author.Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.• Present/permanent address.If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.Abstract:A self-contained abstract of 100 to 200 words, outlining in a single paragraph the aims, scope and conclusions of the paper must be supplied. Do not list the analytical equipment (e.g. SEM, XRD, TEM) used unless it is critical to themeaning. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separate from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, they must be cited in full, without reference to the reference list. Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.KeywordsImmediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, "and", "of"). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.AcknowledgementsCollate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).Nomenclature and unitsFollow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI. You are urged to consult IUGS: Nomenclature for geological time scales/rock names: / for further information.Math formulaePresent simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).ArtworkElectronic artworkGeneral points• Make sure you use uniform lettering and sizing of your original artwork.• Save text in illustrations as "graphics" or enclose the font.• Only use the following fonts in your illustrations: Arial, Courier, Ti mes, Symbol.• Number the illustrations according to their sequence in the text.• Use a logical naming convention for your artwork files.• Provide captions to illustrations separately.• Produce images near to the desired size of the printed version.• Submit each figure as a separate file.A detailed guide on electronic artwork is available on our website:/artworkinstructionsYou are urged to visit this site; some excerpts from the detailed information are given here.FormatsRegardless of the application used, when your electronic artwork is finalise d, please "save as" or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):EPS: Vector drawings. Embed the font or save the text as "graphics".TIFF: color or grayscale photographs (halftones): always use a minimum of 300 dpi.TIFF: Bitmapped line drawings: use a minimum of 1000 dpi.TIFF: Combinations bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is required.DOC, XLS or PPT: If your electronic artwork is created in any of these Microsoft Office applications please supply "as is".Please do not:• Supply embedded graphics in your wordprocessor (spreadsheet, presentation) document;• Supply files that are optimised for scr een use (like GIF, BMP, PICT, WPG); the resolution is too low;• Supply files that are too low in resolution;• Submit graphics that are disproportionately large for the content.Color artworkPlease make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color in print or on the Web only. For further information on the preparation of electronic artwork, please see /artworkinstructions.Please note: Because of technical complications which can arise by converting color figures to "gray scale" (for the printed version should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.Figure captionsEnsure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.TablesNumber tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.ReferencesCitation in textPlease ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either "Unpublished results" or "Personal communication" Citation of a reference as "in press" implies that the item has been accepted for publication.Web referencesAs a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading i f desired, or can be included in the reference list.References in a special issuePlease ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue.

The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. The correct format for citing a DOI is shown as follows (example taken from a document in the journal Physics Letters B): doi:10.1016/j.physletb.2003.10.071When you use the DOI to create URL hyperlinks to documents on the web, theyare guaranteed never to change.ProofsOne set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 (or higher) available free from /products/acrobat/readstep2.html. Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site: /products/acrobat/acrrsystemreqs.html#70win.If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately. Therefore, it is important to ensure that all of your corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received.OffprintsThe corresponding author, at no cost, will be provided with a PDF file of the article via e-mail or, alternatively, 25 free paper offprints. If the corresponding author opts for paper offprints, this preference must be indicated via the offprint order form which is sent once the article is accepted for publication. Additional paper offprints can also be ordered via this form for an extra charge. The PDF file is a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use. Keyword List(被省略)。
