摘要：

The capacitive behavior of various composite thin films composed of polyaniline (PANI) polymerized by cyclic voltammetry and platinum microparticles deposited by potentiostatic or pulse-rest techniques was systematically compared using cyclic voltammetry and chronopotentiometry. These composite films, exhibiting the highly electrochemical reversibility of redox reactions, high power property and good stability between -200 and 600 mV, were demonstrated to be potential candidates for the electrode materials of electrochemical supercapacitors. The effect of the dispersion degree of Pt particles within the composite films on the electrochemical characteristics and stability of the PANI-Pt composite films was discussed. The crystalline information, surface morphologies and platinum distribution profiles of these organic-inorganic composite films were, respectively, characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and Auger electron spectroscopy (AES).
