摘要
聚吡咯以其制备简单、掺杂可逆、环境友好、导电率高、比电容大、具有良好的成膜性而备受关注。特别是在作为超级电容器、二次电池等换能设备电极材料领域中前景广阔。文章简略地介绍了超级电容器的双电层电容和法拉第赝电容产生的机理,概述了近年来聚吡咯与金属氧化物、炭材料等通过化学法、电化学法以及界面化学法等新型手段制备聚吡咯电极的研究进展。
Polypyrrole （PPy） has been received much concern for its simple preparation, reversible doping, environment-friendly, higher conductivity and huge specific capacitance, as well as the better film forming ability. Especially, it has broad prospect as the electrode material of energy conversing devices such as supercapacitor and secondary battery. In this paper, the mechanism of double layer capacity and pseudo capacity of supercapacitor was reviewed simply, and the recent progress of polypyrrole supereapacitor electrode manufactured by different material such as metal oxide, carbon material via chemical, electrochemical or new type method such as interface method was generalized.
