Abstract
The partial decomposition of PF6- during pyrrole electropolymerization in methanol and acetonitrile on Fe and Pt electrodes is demonstrated using XPS analysis. A complex mixture of PF6-, fluorides, oxyfluorides of phosphorus and metal oxides is shown to exist in the interfacial r egion, probably resulting in a weak cohesive layer unfavourable to the adhesion of polymer films.
