ABSTRACT:
A self-supporting conductive polymer film having distributed therein an electrically conductive polymer composition containing linearly conjugated π-electron systems and residues of sulfonated lignin or a sulfonated polyflavonoid. The conductive polymer film preferably has a surface resistivity of from about 102ohms per square to about 1010ohms per square and is preferably formed from a liquid dispersion of thermoplastic polymer having the electrically conductive polymer composition distributed therein. In a preferred embodiment, heat sealable conductive fluoropolymer films are prepared.
