Abstract
A processable, electrically conductive polymer composition comprises a molecular complex made by template guided chemical polymerization and having a polyelectrolyte and a conductive polymer. A process of preparing a processable, electrically conductive polymer composition comprises the steps of oxidative polymerizing the monomers (abbreviated as AN) for a conductive polymer in the presence of a polyelectrolyte which serves first as a template (abbreviated as TEMP) that binds AN to form a template-(AN)n complex; and adding an oxidant to the template-(AN)n complex for conducting an oxidative polymerization to obtain a molecular complex of a polyelectrolyte and a conductive polymer.
