Abstract

Electrical capacitance at the interface between electrolyte solution and conducting polypyrrole film electrode was measured by a simple electrochemical method. The polymer films were electropolymerized in the presence of perchlorate (PPy-ClO4) or Nafion (PPy-Nafion) anions as the dopant ions. Both polymers exhibited large double layer capacitances which were slightly potential dependent within the potential range where the polymers are conductive. The capacitance increased in proportion to the polymer thickness. The specific capacitance were about 10 Fg-1and 44 F g-1 for PPy-Nafion and PPy-ClO4, respectively.
