ABSTRACT:
A method for preparing an electrically conductive polyimide article having a polyimide matrix with carbon black and graphite particles uniformly dispersed therein. The method includes the steps of milling carbon black and graphite in a polar solvent to form a slurry, mixing the slurry with polyamide acid to form a dope, shaping the dope, and converting the shaped material into a polyimide article.
