Abstract
An electrically conductive polyamide/polyphenylene ether resin composition and a molded article for vehicles using the same. The resin composition includes a polyphenylene ether; a polyamide; an olefin-based polymer; an impact modifier; a compatibilizer; and carbon fibrils, wherein the polyphenylene ether and the impact modifier form domains, and the polyamide, the olefin-based polymer and the carbon fibrils form a matrix, the domains including about 90 vol % or more of domain particles having a particle diameter of about 0.1 μm to about 2.0 μm, and wherein the electrically conductive polyamide/polyphenylene ether resin composition has a surface resistance of about 108Ω/□ or less as measured on a specimen having a size of about 100 mm×about 100 mm×about 0.5 mm under conditions of about 23° C. and about 50% relative humidity (RH). The electrically conductive polyamide/polyphenylene ether resin composition and the molded article for vehicles using the same can exhibit good properties in terms of mechanical strength, heat resistance, impact resistance and electrical conductivity.
