▎ 摘  要

NOVELTY - Coating comprises 48-60 wt.% graphene, 10-25 wt.% conductive silver powder and 25-40 wt.% resin. USE - The coating is useful for preparing high conductive graphene radiating copper foil/conductive cloth (claimed). ADVANTAGE - The coating has excellent conductivity, and certain ability to conduct current and dissipate static charge. The method is simple and efficiently reduces cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing the coating, comprising (i) adding graphene and conductive silver powder into ball mill, uniformly mixing and grinding to obtain a composite powder, and (ii) dissolving resin in ethanol, simultaneously adding composite powder, and ultrasonically dispersing at 50-60 degrees C for 30-50 minutes; and (2) a method for preparing high conductive graphene radiating copper foil/conductive cloth, comprising adopting various coating methods e.g. scraper, gravure coating, and slit coating, coating the coating on the surface of copper foil or conductive cloth with a coating thickness of 3-5 mu m, and drying in an oven.
