摘要
采用原位聚合法制备聚苯胺(PANI)、PANI/氧化石墨烯(GO)复合材料和PANI/还原氧化石墨烯(RGO)复合材料。利用四探针测试仪、X射线衍射(XRD)仪、傅立叶变换红外光谱(FTIR)仪、热重(TG)分析仪和扫描电子显微镜(SEM)等对PANI及PANI/GO复合材料和PANI/RGO复合材料进行表征。电导率测试结果表明,当加入GO质量分数为50%时,先还原后聚合法制得PANI/RGO复合材料的导电率可达9.916 S/cm,RGO能有效提高复合材料的导电性;XRD和FTIR分析结果表明,GO和RGO都能较好分散在PANI中;TG分析结果表明,将GO还原为RGO后在小于250℃时能有效提高复合材料的热稳定性。通过原位聚合法能将GO和RGO较好分散在PANI中,形成较好的插层型复合材料,尤其是先还原后聚合法制得的PANI/RGO复合材料具有较好的导电性和热稳定性。
Polyaniline(PANI),PANI/graphene oxide(GO)composites and PANI/reduced graphene oxide(RGO)composites were prepared by in-situ polymerization.PANI,PANI/GO and PANI/RGO composites were characterized by four-probe tester,XRD,FTIR,TG analysis and SEM.The four-probe test result shows that the electrical conductivity of PANI/RGO composite prepared by reducing and polymerization is9.916S/cm when the mass fraction of GO is50%,the conductivity of composite has improved by adding RGO.XRD and FTIR analysis results show that GO and RGO are dispersed in PANI well.TG analysis shows that the thermal stability of the composite can be effectively improved below250℃after reducing GO to RGO.The characterization results show that GO and RGO are dispersed in PANI very well.High quality PANI/RGO composite is prepared by reductionpolymerization.PANI/RGO composite has good conductivity and thermal stability.
