摘要：

Impedance studies of polypyrrole films having different thicknesses and a fitting to an equivalent circuit have been made. In this equivalent circuit the charge transfer corresponding to parallel reactions is included. The results reveal that the charge-storage capacity of the polymer films varies with the applied potential, and is proportional to the thickness of the polymer film. The evolution of the capacity with the potential is similar to that observed on a voltammogram obtained in the background electrolyte.
