Criteria governing ion and solvent transport rates in electroactive polymers: the existence of kinetic permselectivity

Abstract

Ion and solvent transport in polythionine and polyvinylferrocene films have been monitored under transient conditions using the electrochemical quartz crystal microbalance. Film sources of required species are utilized before solution-phase sources. Potential gradients within the film influence ion motion, resulting in a diversity of transport rates which can give rise to transient permselectivity.
