Abstract

An electrically conductive elastomer for grafting to thermoplastic and thermoset substrates is disclosed. If the substrate is a thermoset substrate, the electrically conductive elastomer comprises a mixture of an elastic material, a quantity of electrically conductive flakes, a thermoplastic elastomer material, and a thermoset material. If the substrate is a thermoplastic substrate, the electrically conductive elastomer comprises a mixture of an elastic material, a quantity of electrically conductive flakes, a thermoplastic elastomer material, and a thermoplastic material. The electrically conductive elastomer may further comprise a quantity of electrically conductive particles interspersed within the mixture. Alternatively, a quantity of electrically conductive particles may be imbedded in an outer surface of the electrically conductive elastomer. The electrically conductive elastomer is typically grafted to the substrate by a thermal process.
