Properties of electrochemically synthesized polymer electrodes—IX. The effects of surfactants on polypyrrole films

Abstract The electrochemical behaviour of polypyrrole film electrodes synthesized in the presence of sodium dodecylsulphate, has been investigated by cyclic voltammetry and frequency response analysis. The results indicate that the surfactant anion favours redox processes which are faster and more reversible than those associated to usual polypyrrole electrodes. The modified, surfactant-based polypyrrole electrodes have been successfully used in lithium, organic electrolyte batteries having improved power density and cyclability characteristics.
