Preparation and Characterization of Polyheterocycle/Polyelectrolyte Molecular Composites
Abstract
The electrochemical preparation of polyheterocycle polyelectrolyte molecular composites of high electrical conductivity, mechanical integrity and specific ion transport has been pursued. A water soluble polyelectrolyte derivative of Kevlar has been developed and utilized as electrolyte in the electropolymerization of pyrrole to yield polypyrrole/poly(p- phenyleneterephthalamide propane sulfonate). This material exhibits conductivities up to 1 ohm/cm and improved thermal stabilities when compared to typical polypyrroles. The electropolymerization/deposition of polyheterocycle/ polyelectrolyte molecular composites, specifically polypyrrole/poly(styrene sulfonate), yields electrically controllable membranes with cation specific transport. Electrochemical quartz microbalance studies have been used to analyze composite formation and ion transport.
