Abstract: The present invention is an ignition resistant polymeric composite comprising a) a polymeric substrate; b) a flame retardant intermixed with the polymeric substrate; and c) a partially oxidized plasma polymerized organosilicon layer adhered to the substrate. The ignition resistant composite can readily achieve a V-0 rating in a UL-94 flammability test using a substantially lower concentration of flame retardant than is commonly incorporated into substrates to achieve the same result. Consequently, the present invention addresses the need to maintain the integrity of a substrate incorporated with flame retardant to reduce the levels of environmentally suspect materials.

Abstract: A process for creating plasma polymerized deposition on a substrate by a corona discharge is described. The corona discharge is created between an electrode and a counterelectrode supporting a substrate. A mixture of a balance gas and a working gas is flowed rapidly through the electrode, plasma polymerized by corona discharge, and deposited onto the substrate as an optically clear coating or to create surface modification. The process, which is preferably carried out at or near atmospheric pressure, can be designed to create an optically clear powder-free or virtually powder free deposit of polymerized plasma that provides a substrate with properties such as surface modification, chemical resistance, and barrier to gases.
