氧化石墨掺杂的电化学活性自支撑聚苯胺膜

High Electrochemical Activities of Polyaniline Doped with Graphene Oxide Free-standing Film

以氧化石墨(GO)为掺杂剂和模板,采用化学原位聚合法,通过调节苯胺单体和氧化石墨的质量比,合成了层状结构的聚苯胺/氧化石墨(PANI/GO)自支撑膜.SEM和XRD研究结果表明,当苯胺单体与GO的质量比为67∶1时,PANI/GO复合材料具有层间距约1.36 nm的层状结构,证实GO的模板功能.XPS和FTIR研究结果表明,PANI/GO复合材料具有典型的聚苯胺掺杂态,进一步证实GO的掺杂功能.此外,电化学和热失重测量结果表明,PANI/GO层状结构的自支撑膜呈现良好的热稳定性和高电化学活性.

The electrochemical activated polyaniline/graphene oxide（PANI/GO） inter-layered free-standing film was synthesized in the present of GO used as dopant and hard-template,by adjusting the mass ratio of {PANI} to GO.The composite layered structure was measured by means of SEM,and the interlayer distance is calculated to be 1.36 nm with the XRD measurement.The XPS and FTIR studies proved PANI in the composite structure is in the emeraldine state form.Moreover,the PANI/GO composite free-standing film performs high thermal stability and electrochemical activity.
