Conducting polypyrrole thin films, doped with sodium-p-toluenesulfonate (Na-pTS) and potassium-hydroquinone monosulfate (K-HQS), were prepared by electrochemical oxidation of pyrrole on indium-tin-oxide/glass substrates. The optical band gaps of the doped polymer materials were determined from their...
