Abstract

A molecular complex which comprises a biopolymer having a plurality of ionic functional groups and a conductive polymer having charges therein. The charges bind to the ionic functional groups to form the complex. The conductive polymer is selected from the group consisting essentially of polyaniline, polypyrrole, polythiophene, poly(phenylenevinylene) or poly(phenylene sulfide) and substituted versions thereof.
