Both PPy film and Ta2O5 layer are simultaneously formed on Ta-electrode by one process of electrical oxidation in an aqueous solution. Preparation of the structure (PPy/Ta2O5/Ta) can also takes place by the electrolysis using Ta-electrode on which PPy is formed previously by electropolymerization. Since PPy film obtained by the former method has higher electric conductivity (110 S/cm) and better adhesion than the later, (PPy/Ta2O5/Ta)structure formed simultaneously is confirmed better electrical properties as a capacitor.
