Abstract

The ion transfer in redox processes of conducting polypyrrole doped with various anions, such as 1-naphthalenesulfonate, 10-camphorsulfonate, p-toluenesulfonate, dodecylbenzenesulfonate was investigated by electrochemical quartz crystal microbalance (EQCM), contact electric resistance (CER), and cyclic voltamperometry in situ techniques. By using this setup, the doping levels of the synthesized PPy films and mobility of charge carries in these materials in KCl aqueous solution under linear potential scan were determined.
