Abstract

Electrically conductive and mechanically strong PPTA [Kevlar]-polypyrrole hybrid fibers have been prepared by an approach that capitalizes upon the solubility of metalated PPTA in certain polar organic solvents. Thus, DMSO solutions of NNa PPTA were dry-jet wet-spun into an FeCl3·6H2O-containing coagulation bath to yield flexible PPTA-polypyrrole hybrid fibers containing greater than 50 wt % of polypyrrole. Room temperature conductivities approaching 10 S/cm are observed. Variable-temperature conductivity and thermoelectric power data correspond closely to those of high-quality polypyrrole films.
