摘　　要：石墨烯因其优异的导电性能和巨大的比表面积而被广泛应用于复合材料的研究。本文借助微晶石英天平采用循环伏安法一步电沉积制备了聚苯胺/石墨烯复合材料,其中所用到的石墨烯分散液是电解剥离法制备的。保持苯胺单体的浓度不变,观察改变石墨烯的含量对聚苯胺/石墨烯复合材料的制备的影响。结果表明,制得的复合材料的比电容高达1166 F/g。当苯胺单体浓度不变时,石墨烯的含量越高,循环伏安结果表明其电容性能也越好。所得的聚苯胺/石墨烯复合材料中石墨烯起到了良好的电子传输作用。Graphene was widely used in the research of composite materials because of its excellent conductive properties and specific surface area. Polyaniline/graphene composites were prepared using cyclic voltammetry one - step eleetrodeposition by quartz crystal microbalance in this paper. The used graphene dispersion was made by electrolytic stripping method. Remaining concentrations of aniline the same, the influence of graphene content on preparation of polyaniline/graphene composites was observed. The results showed that the specific capacitor reached up to 1166 F/g. The higher content of graphene demonstrated better electronic transmission function, with the same concentrations of aniline. Meanwhile, the cyclic vohammograms results indicated better performance of the capacitor.
