Abstract
Organically soluble intrinsically conductive polymer compositions having enhanced electrical conductivity are produced by adding a hygroscopic, water-insoluble plasticizer to an organically soluble intrinsically conductive polymer salt. Polymer blends containing such compositions are also produced by blending a matrix polymer with the plasticizer/ICP salt compositions. Methods for enhancing the electrical conductivity of an organically soluble intrinsically conductive polymer salt provide for the addition of a hygroscopic, water-insoluble plasticizer to an organically soluble intrinsically conductive polymer salt.
