氧化石墨烯纳米片在室温以上的酸性水介质中容易被苯胺还原，苯胺同时进行氧化聚合，生成还原的氧化石墨烯-聚苯胺纳米纤维（RGO-PANi）复合材料。采用XPS、XRD、TGA、紫外可见吸收光谱、TEM等手段对合成的氧化石墨烯-聚苯胺复合材料和聚苯胺溶解后的氧化石墨烯进行了表征。RGO-PANi复合材料作为电容器电极，在恒流充放电过程中表现出良好的比电容。
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.
