Abstract
A method is described for producing electrically-conductive paths in poly(arylene sulfide) and other polymers exhibiting differing receptivity to chemical doping agents depending upon the crystallinity of the polymer structure. Conductivity is selectively induced in amorphous regions by contacting the amorphous regions with a doping agent in solution. Selected areas of crystalline polymers are made amorphous by heat or solvent treatment.
