Abstract: Polyaniline was fabricated by cyclic voltammetry on the surface of Pt electrode in organic solvent.Cyclic voltammetry, galvanostatic charge were used to detect the performance of the polvaniline electrode.The experiment results demonstrated that the potential-time curves was linear, and the rectangular CV curves exhibited typical capacitive behavior of the electrode with a specific capacitance up to 320.8F/g.The electrode also showed excellent cyclic life.
