Polypyrrole thin film microelectrodes prepared from an aqueous solution of the sodium salt of 1, 2-napthaquinone-4-sulfonic acid and pyrrole in hydrochloric acid as the supporting electrolyte was characterized electrochemically for the first time and found to exhibit good electronic and spectroscopic properties. Voltammetric investigations showed that the polymer exhibited quasireversible kinetics in a potentia...
