▎ 摘  要

NOVELTY - Preparing superhydrophilic reduction-graphene oxide coating, comprises (i) preparing the graphene oxide by the Hummers method, washing the reaction product to neutral, and dispersing in water to form an aqueous graphene oxide solution, (ii) performing ultrasonic peeling and centrifugation on the graphene oxide aqueous solution to obtain 0.2 to 2 mg/ml graphene oxide aqueous dispersion, (iii) adding 0.1-0.3 wt.% carboxymethyl cellulose aqueous solution to the graphene oxide aqueous dispersion, the amount of which is 5-10 V/V% of the graphene oxide aqueous dispersion to prepare a uniform mixed liquid, (iv) coating the mixed solution on a carrier to obtain a carrier with a coating layer, and (v) heat-treating the carrier with a coating layer. USE - The method is useful for preparing superhydrophilic reduction-graphene oxide coating. ADVANTAGE - The method is simple and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for coating product for preparing a superhydrophilic reduction-graphene oxide coating.
