STABILITY OF GRAPHENE FILMS ON COPPER, SILICON AND GLASS SUBSTRATES IN CONTACT WITH BOILING WATER

The stability of graphene coatings deposited on substrates made of glass, single-crystal silicon with an oxide layer, and copper in contact with boiling water was experimentally tested. It was shown that multilayer graphene coatings are stable: they are not destroyed or peeled off from the substrates bound to them by van der Waals forces during boiling. However, when using a graphene coating obtained by the electric arc method, the adhesion of graphene films is not sufficient. Therefore, when boiling, they are destroyed. The technology of graphene coating synthesis and transfer proposed in this work can be used to create heating elements and heat-exchange devices based on graphene.
