Redoping — A simple way to enhance the redoxcapacity of polypyrrole films

In this work, the beneficial structural properties of polypyrrole (PPy) films formed in the presence of benzenesulfonate (BS) and para-toluenesulfonate ( pTS) were combined with the good mobility of small inorganic anions as chloride by redoping (ion exchange). the combination of voltammetry as the...

Summary:In this work, the beneficial structural properties of polypyrrole (PPy) films formed in the presence of benzenesulfonate (BS) and para-toluenesulfonate ( pTS) were combined with the good mobility of small inorganic anions as chloride by redoping (ion exchange). the combination of voltammetry as the classical method for the determination of redoxcapacity together with the analytical determination of the doping level before and after redoping by X-ray microanalysis (EDS) allow to optimize the redoping process and produce PPy films with high redoxcapacity and stability.
