Polyaniline doped with hydrochloric acid was prepared by chemical polymerization,and polyaniline/polysulfone composite film electrode was obtained by mixing the doped polyaniline with the polysulfone solution,and quantitatively adding the mixture to the glassy carbon electrode. The morphology and structure of polyaniline were characterized by scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FTIR) and X-ray diffraction(XRD). The electrochemical properties of supercapacitor were investigated by cyclic voltammetry, galvanostatic charging-discharging and electrochemical impedance spectroscopy. These results show that polyaniline/polysulfone composite with porous structure has good capacitance performance,and a specific capacitance of 497 F/g is obtained. The composite also exhibits lower inter resistance and good cycle stability.
