摘要

以生物制剂肝素钠为掺杂剂,由自组装方法合成出平均粒径为100 nm的球状聚吡咯(PPy),用作超级电容器电极材料.透射电镜(TEM)、循环伏安、恒流充放电和电化学交流阻抗测试表明,肝素钠掺杂聚吡咯呈现较好的形貌和电容性质,在电流密度3 mA/cm2下充放电,单电极比电容达到338 F/g.

Abstract

Spherical-like polypyrrole with an average diameter of 100 nm as the electrode material for supercapacitor was prepared by a self-assembly process with heparin sodium salt as the dopant at-10 ℃.The morphology and electrochemical properties were characterized by transmission electron microscopy(TEM),cyclic voltammetry(CV),galvanostatic charge/discharge and electrochemical impedance spectroscopy(EIS) measurements.The results showed that the polypyrrole doped with heparin sodium salt exhibited good capacitive behavior.The specific capacitance of single electrode was up to 338 F/g at 3 mA/cm2.
