Coating system for protecting a substrate

Abstract

The present invention relates to a coating system for protecting a substrate comprising at least one layer A and at least one layer B, wherein said layer A is made of a material selected from the group consisting of pyrolytic graphite, pyrolytic boron nitride, compressed expanded graphite, hot-pressed turbostratic boron nitride, compressed graphene flakes, compressed hexagonal boron nitride flakes, graphitized graphene oxide flakes or a combination thereof; and said layer B is made of a composite comprising a polymeric matrix and 2D flakes, said 2D flakes being made of a material selected from the group consisting of graphene, graphene oxides, reduced graphene oxide, heteroatom-doped graphene, hexagonal boron nitride, metal chalcogenides, metal oxides, metal chalcogenide halides, metal halides, phosphotrichalcogenides, MXenes, metal carbides, metal nitrides, layered hydroxides, alkaline-earth metal silicides, alkaline-earth metal bromides, alkaline-earth metal germanides and alkaline-earth metal stannides, layered peroskivtes, phosphorene, silicene, antimonene, germanene, boronene, stanene, bismuthene and combination thereof. It further relates to a coated substrate comprising a substrate and the coating system.
