摘　　要：采用原位聚合法制备聚苯胺/石墨烯复合材料,以石墨烯与聚苯胺的摩尔比1∶3、1∶6、1∶10进行实验。探究后发现1∶6为最佳比例,其比电容可达513 F/g。再以一定量聚乙烯醇掺杂最佳比例聚苯胺/石墨烯,结果发现,所得复合材料应用与超级电容器中,最高比电容可达1044 F/g,经2000次充放电循环后,其比电容仍有916 F/g,证明复合材料稳定性远远大于聚苯胺稳定性。采用XRD、FT-IR、SEM、紫外-可见分光光度计进行结构和微观形貌分析。Polyaniline/graphene composites were prepared by in-situ polymerization,and the molar ratio of graphene to polyaniline was 1∶3,1∶6 and 1∶10.It was found that 1∶6 had the best ratio and its specific capacitance could reach 513 F/g.The polyaniline/graphene with optimum proportion doped with trace polyvinyl alcohol.The results showed that the maximum specific capacitance of the composites could reach 1044 F/g.After 2000 cycles of charge and discharge,the specific capacitance of the composites was still 916 F/g,which proved that the stability of the composites was much greater than that of polyaniline.It was characterized by XRD,FT-IR,SEM,TEM and UV-Vis spectrophotometer.
