Abstract

Mechanically strong, environmentally stable, and electrically conductive polymeric films and fibers can be fabricated by processing (dry-jet, wet-spinning) solutions of PPBT and metallophthalocyanine molecular metal precursors, followed by chemical or electrochemical oxidation. X-ray diffraction, and resonance Raman measurements on (PPBT)-[Ni(Pc)I]x fibers indicate a microstructure consisting of small Ni(Pc)I crystallites imbedded in a PPBT matrix. Cyclic voltammetry and controlled potential coulometry indicate that PPBT/NiPc films can be reversibly doped.
