Abstract
Fabrics are made electrically conductive by contacting the fabric under agitation conditions with an aqueous solution of a pyrrole or aniline compound, and an oxidizing agent and a doping agent or counter ion; and then epitaxially depositing onto the surface of the individual fibers of said fabric the in status nascendi forming polymer of the pyrrole or aniline compound so as to uniformly and coherently cover the fibers with an ordered conductive film of the polymerized pyrrole or aniline compound. Individual fibers and yarns can be similarly treated and then formed into fabrics. Products made by the process are also described.
Claims13
An electrically conductive textile material which comprises a textile material made predominantly of fibers selected from polyester, polyamide, acrylic, polybenzimidazole, glass and ceramic fibers;
- wherein said textile material is covered to a uniform thickness of from about 0.05 to about 2 microns through chemical oxidation in an aqueous solution with a coherent, ordered film of an electrically conductive, organic polymer selected from a pyrrole polymer and an aniline polymer.
