Abstract

The electrochemical activities of polypyrrole/polyethylenglycol (Ppy/PEG) composite films are examined using cyclic voltammetry, electrochemical impedance spectroscopy and scanning electron microscopy. It is observed that the electroactivity and charge transfer kinetics are a function of the PEG concentration used during the pyrrole electropolymerization process. Through an adequate transfer function the impedance data of the polymer systems are fitted and the electric parameters are evaluated and discussed as a function of the synthesis conditions of the formed films at different PEG concentration and its morphology.
