▎ 摘  要

NOVELTY - Graphene slurry comprises 0.1-5 wt.% graphene, 1-10 wt.% filler, 70-90 wt.% solvent, 5-30 wt.% binder, 0.1-2 wt% dispersant and 0-3 wt.% functional additive. USE - The graphene slurry is useful for metal coating, in the field of heat exchange e.g. air conditioner, car or cold water machine field (claimed). ADVANTAGE - The graphene slurry has excellent film forming performance and the formed coating has excellent corrosion resistance, mildew proof, antibacterial property and thermal conductivity and coated aluminum foil is useful for heat dissipating fins, eliminating condensation on the surface during cooling and reducing wind resistance, improves the corrosion resistance of the coating, enhances the thermal conductivity of the coating and increases the radiance of the coating, by improving the heat exchange efficiency of the air-conditioning aluminum foil, reduces energy consumption and improves the energy efficiency ratio can be applied to air conditioners, automobiles and chillers. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing graphene slurry comprising adding graphene, filling, solvent, binder, dispersant, functional additive at high speed dispersing, sand grinding and mixing; (2) graphene coating comprising graphene slurry for metal coating, where the graphene coating has a thickness of 0.5-10 mu m; and (3) device comprising a substrate and the graphene coating formed on a substrate, where the substrate comprising metal foil and the metal foil comprising aluminum foil.
