    Abstract

    Pyrrole was electrochemically polymerised onto gold electrodes at a fixed potential of 0.80 V vs. SCE to generate polypyrrole (PPy). Depending on the pH of the solution, PPy, was deposited in either a bulk or nanowire conformation. Electrochemical impedance spectroscopy, EIS, experiments were subsequently carried out on a bare gold electrode, PPy nanowires and bulk PPy of two different film surface areas. The impedance data were analysed using equivalent circuits giving information on the electrochemical properties of the polymers. The influence of different electrolytes on the impedance was also examined.
