摘要

应用化学氧化聚合法制备了超级电容器用聚苯胺电极材料.FTIR、SEM及电化学电容测试表明:聚苯胺由纳米颗粒堆积而成,颗粒大小50nm左右;在H2SO4、NaNO3或KOH电解液(浓度均为1mol/L)中,5mA/cm2电流密度下,PANi电极比电容分别为404F/g、208F/g和279F/g;如H2SO4浓度升高至2mol/L或6mol/L,比电容明显下降,仅为330F/g或248F/g.

Abstract

The polyaniline(PANi) for supercapacitor was prepared by chemical-oxidative polymerization.The SEM,FTIR data and electrochemical performance showed that,polyaniline nanoparticles were formed which were about 50 nm;the specific capacitances of PANi were 404 F/g,208 F/g and 279 F/g in 1 mol/L H2SO4,NaNO3 and KOH,respectively,when the current density was 5 mA/cm2.The concentrations of H2SO4 increased to 2 mol/L or 6 mol/L,the capacitances decreased to 330 F/g or 248 F/g.
