▎ 摘  要

NOVELTY - Generating a graphene coating on the surface of a glass comprises (i) dispersing the oxidized graphene in pure water; (ii) preparing mixed solution of ammonium fluoride and ammonium bromide; (iii) adding the mixed solution obtained into the graphene oxide dispersion obtained at room temperature, allowing to stand, and using ammonium ions partially to reduce graphene oxide to make it into a gel; (iv) coating the graphene oxide gel on the glass surface, and heating and drying; and (v) using the non-woven fabric to wipe the graphene not combined with the glass. USE - The method is useful for generating a graphene coating on the surface of a glass. ADVANTAGE - The method: strengthens the coating by utilizing the compound effect produced by ammonium ions, fluorine ions and bromide ions in the reduction process of graphene oxide; and enables to generate graphene coating on the surface of a glass which prolongs the service life of the coating graphene on surface of the glass, and increases the scratch-resistant degree of the generated coating.
