▎ 摘　　要

NOVELTY - A graphene coating comprises 5-95 wt.% graphene at thickness of less than or equal to 10 nm, 5-95 wt.% adhesive, 0.01-50 wt.% dispersant and/or surfactant, 0.01-10 wt.% antifoaming agent and balance solvent. USE - Graphene coating. ADVANTAGE - The coating is suitable for metal surface including print circuit, electronic device, radio frequency device, screen, solar energy thin film and LED. The coating has increased electric conduction/conductivity and oxidation properties, improved corrosion resistance, and reduced friction resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for (1) preparation of graphene coating comprising taking raw materials, mixing, and dispersing; and (2) application of graphene coating comprising taking graphene coating, diluting to 0.5-10 wt.% solid content, cleaning substrate surface, coating, and drying at 50-200 degrees C for 1-24 hours.
