Abstract
A graphene oxide-coated graphitic foil, composed of a graphitic substrate or core layer having two opposed primary surfaces and at least a graphene oxide coating layer deposited on at least one of the two primary surfaces, wherein the graphitic substrate layer has a thickness preferably from 0.34 nm to 1 mm, and the graphene oxide coating layer has a thickness preferably from 0.5 nm to 1 mm and an oxygen content of 0.01%-40% by weight based on the total graphene oxide weight. The graphitic substrate layer may be preferably selected from flexible graphite foil, graphene film, graphene paper, graphite particle paper, carbon-carbon composite film, carbon nano-fiber paper, or carbon nano-tube paper. This graphene oxide-coated laminate exhibits a combination of exceptional thermal conductivity, electrical conductivity, mechanical strength, surface smoothness, surface hardness, and scratch resistance unmatched by any thin-film material of comparable thickness range.
