Electrochemical Investigation of Electronically Conductive Polymers
Abstract
A small amplitude current-pulse method which is uniquely suited for solving the myriad problems associated with electrochemical analyses of electronically conductive polymers has been developed. This method was used to obtain Dapp values for the electronically conductive polymer, polypyrrole. The results of these experiments are described here. In addition, a procedure for controlling the morphologies of electronically conductive polymers has been developed. This procedure involves the electrochemical growth of the conductive polymer at an electrode surface which has been masked with a microporous polymer membrane. The pores in this membrane act as templates for the nascent electronically conductive polymer. Because the template membrane contains linear cylindrical pores, cylindrical conductive polymer fibrils are obtained. We will show in this manuscript that microfibrillar polypyroole films prepared via this approach can support higher rates of charge-transport than conventional polypyrrole.
