Electrochemical Polymerization of Pyrrole from Aqueous Solutions : 2. Growth Kinetics of Polypyrrole p-toluenesulfonate Film
Eui Hwan Song, Woon Kie Paik*, Jung Kyoon Chon
The rates of electropolymerization of pyrrole from aqueous solutions containing p-toluenesulfonic acid were studied as functions of the concentration of the surfactant anions and of temperature for the polymerization on the electrode surface immersed in the solution and also for the polymerization along the solution surface. In the case of the solution-surface polymerization, the polymerization rate showed maximum as the concentration of the p-toluenesulfonic acid changed at a fixed temsperature or as the temperature was varied at a fixed concentration. The decrease of the polymerization rate with increasing concentration or with rising temperature beyond the values at the maxima is interpreted as resulting from micelle formation.
