Patent attributes
An electrically conductive hybrid polymer material is described herein. The hybrid polymer material includes 0.01% to 1% by weight of carbon nanoparticles, 1% to 10% by weight of a conductive polymeric material, 1% to 20% of electrically conductive fibers having a metallic surface and 69% or more by weight of a nonconductive polymeric base material. The carbon nanoparticles may be carbon nanotubes, graphite nanoparticles, graphene nanoparticles, and/or fullerene nanoparticles. The conductive polymeric material may be an inherently conductive polymer, a radical polymers, or an electroactive polymer. The electrically conductive fibers may be stainless steel fibers, metal plated carbon fibers, or metal nanowires. The nonconductive polymeric base material may be selected from materials that are pliable at temperatures between −40° C. and 125° C. or materials that are rigid in this temperature range. The hybrid polymer material may be used to provide EMI shielding for wire cables of housings of electrical assemblies.
