Abstract
A conductive (electrical, ionic, and photoelectric) polymer membrane article, comprising a non-woven membrane of polymer fibers, wherein at least some of the fibers have diameters of less than one micron; and wherein the membrane has an electrical conductivity of at least about 10−6 S/cm. Also disclosed is the method of making such an article, comprising electrostatically spinning a spin dope comprising a polymer carrier and/or a conductive polymer or conductive nanoparticles, to provide inherent conductivity in the article.
