▎ 摘　　要

NOVELTY - Preparing graphene oxide-tannic acid/aqueous epoxy composite paint, comprises (1) adding 100 ml deionized water and 0.05 g tannic acid into a 250 ml beaker, and ultrasonic oscillating for 20 minutes to obtain a tannic acid solution, adding 0.1 g graphene oxide under ultrasonic oscillating condition (600 W), then dispersing in the tannic acid solution for 1 hour to obtain tannic acid intercalated graphene dispersion, then removing unreacted graphene oxide and tannic acid in the mixed solution through high speed centrifuge (speed of 1000-1500 revolutions/minute) to obtain a graphene oxide-tannic acid dispersing solution, and (2) mixing base material with the graphene oxide-tannic acid dispersing solution under stirring condition to form uniformly dispersed system, transferring the uniformly dispersed system into a spray gun, sand blasting high pressure spraying surface by a rectangular steel sheet, curing at room temperature for 2 days. USE - The method is useful for preparing graphene oxide-tannic acid/aqueous epoxy composite paint. ADVANTAGE - The graphene oxide-tannic acid/aqueous epoxy composite paint has improved anticorrosive ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide-tannic acid/aqueous epoxy composite paint obtained by above mention method.
