在不同水醇比的溶剂环境下,利用原位聚合法制得聚吡咯/氧化石墨烯复合物,再经还原得到聚吡咯/还原氧化石墨烯复合材料.通过红外光谱、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等测试方法对复合材料的结构和形貌进行表征,利用电化学工作站对复合物的电化学性能进行了测试.结果表明,在不同水醇比的溶剂条件下所制备的还原氧化石墨烯与聚吡咯复合材料都具有优异的电容性能和良好的稳定性.当水醇比为9∶1(体积比,下同)时,所制备的材料具有最稳定的电容性能.%A series of composites of polypyrrole and graphene oxide (GO) were synthesized by in-situ-polymerization with different ratios of water to alcohol in the solvents for the blending of GO and Py monomer.The structures and morphologies of the resultant composite materials were characterized by infrared spectroscopy,SEM,and TEM,while electrochemical performances were tested by means of cyclic voltammetry (CV) and galvanostatic charge-discharge test.The results showed that all the composite materials have outstanding capacitive performances and good stabilities,and the composite synthesized under 9 ∶ 1 water-alcohol ratio (volume ratio) exhibits the most stable capacitive performance.
