▎ 摘　　要

NOVELTY - Super-hydrophobic graphene coating (100 wt.%) comprises 10-20 wt.% filler, 8-12 wt.% polyurethane, 3-5 wt.% graphene, 65-73 wt.% solvent and 1-5 wt.% additive, where the filler comprises PTFE. USE - The coating is useful for preparing a super-hydrophobic coating on surface of a metal substrate (claimed). ADVANTAGE - The coating has excellent hydrophobicity, self-cleaning effect and heat-dissipation performance, and corresponding waterproof and anti-corrosion functions, and makes it difficult for contaminants, such as liquid and dust to adhere to the surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the coating, involves mixing filler, polyurethane, graphene, solvent and additive to obtain the product.
