Films of the conductive polymer PPy (polypyrrole) are prepared by electrochemical synthesis under constant current conditions from aqueous solutions containing pyrrole and p-TS (p-toluene sulphonate). Silicon water is used as the anode, while gold-plated stainless steel is used as the cathode. Measurements on the films of p-TS-doped polypyrrole PPy(p-TS) formed on the anode show a T-1/4 dependence of the logarithm of resistivity, consistent with a three-dimensional variable-range hopping mechanism electrical conduction.
