Polyaniline modified graphene layers/graphite plate (GL/GP/PANI) electrodes were prepared by electrochemical polymerization of aniline on graphene layers/graphite electrodes, which were obtained via in-situ formation of graphene layers on graphite plate by electrochemical exfoliation. The effect of polymerization cycle to specific capacitance of GL/GP/PANI was investigated. The surface features of the electrodes were characterized by SEM. The electrochemical performances of the electrodes were measured in 0.5 M H2SO4 electrolyte, including cyclic voltammetry, galvanostatic charge-discharge and electrochemical stability test. The results indicated that the PANI on the GL/GP electrodes had rodlike structure. At current density of 0.085 mA/cm2, the specific capacitance GL/GP/PANI reached 1 042.8 F/g. This study provided a new way to fabricate substrate electrode material for supercapacitor.
