ABSTRACT:
An electrically conductive shaped article such as a film or fibrous material and a process for preparing the same from a polybenzimidazole shaped article is provided. The polybenzimidazole article is first contacted with cuprous ions to produce a cuprous ion-impregnated material, and subsequently is subjected to a sulfiding agent capable of sulfiding cuprous ions, and preferably washed, to produce a polybenzimidazole shaped article having covellite copper sulfide in association therewith. Also provided are electrically conductive composites and a process for preparing the same by incorporating fibrous material prepared in accordance with the process within a substantially continuous polymeric matrix.
