Abstract

Magnetic fields were applied to the electropolymerization of pyrrole as a novel technique to control the properties of conducting polymers. The p-toluenesulfonate-doped polypyrrole films prepared in the magnetic fields exhibited a more negative cathodic peak in the cyclic voltammograms. This voltammetric change at the reduction process was explained as change from the anion undoping to the cation doping, and such dopingundoping behavior was confirmed by the measurements of electrochemical quartz crystal microbalance.
