Graphene oxide (GO) nanosheets are readily reduced by aniline above room temperature in an aqueous acid medium, with the aniline simultaneously undergoing oxidative polymerization to produce the reduced graphene oxide-polyaniline nanofiber (RGO-PANi) composites. The resulting RGO-PANi composites and RGO (after dissolution of PANi) were characterized by XPS, XRD analysis, TGA, UV-visible absorption spectroscopy, and TEM. It was also found that the RGO-PANi composites exhibit good specific capacitance during galvanostatic charging-discharging when used as capacitor electrodes.
氧化石墨烯（GO）纳米片在室温以上的酸性水溶液中很容易被苯胺还原，同时苯胺发生氧化聚合反应生成还原氧化石墨烯-聚苯胺纳米纤维（RGO-PANi）复合材料。所得的 RGO-PANi 复合材料和 RGO（在 PANi 溶解后）通过 XPS、XRD 分析、TGA、UV-可见吸收光谱和 TEM 进行了表征。还发现，当用作电容器电极时，RGO-PANi 复合材料在恒电流充放电过程中表现出良好的比电容。
