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.
