采用了一种简单有效地方法制备了高电活性的石墨烯/聚苯胺复合材料。首先,将苯胺在氧化石墨烯（GO）的水性分散液中氧化聚合,制备了氧化石墨烯/聚苯胺（GO/PANI）,再将GO/PANI与水合肼反应,制得还原-氧化石墨烯/聚苯胺（R（GO/PANI））。利用透射电子显微镜（TEM）,热失重分析（TGA）和循环伏安法（CV）对GO/PANI和R（GO/PANI的形貌,热稳定性和电化学性能进行了分析研究。结果表明,GO表面存PANI,且R（GO/PANI）的热稳定性和电活性都明显高于GO/PANI。

A graphene oxide/polyaniline naocomposites with high electroactivity was developed.Firstly,a graphene oxide/polyaniline（GO/PANI） composites was prepared by the oxidation polymerization of aniline in graphene oxide（GO） dispersions.Secondly,a reduced graphene oxide/polyaniline（R（GO/PANI）） composites was obtained by the reduction of GO/PANI composites,using hydrazine hydrate as the reducing agent.Transmission electron microscopy（TEM）,thermal gravimetric analysis（TGA） and cyclic voltammogram（CV） were employed to investigate the surface,thermal property,and electroactivity of the samples.TEM results revealed that polyaniline（PANI） was polymerized on the surface of GO sheets.The results of thermal TGA and CV indicated that both the thermal stability and the electroactivity of R（GO/PANI） composites were distinctly higher than those of GO/PANI composites.
