▎ 摘　　要

NOVELTY - Preparation of graphene anti-corrosion antifouling nanomaterial comprises performing silanization treatment of zinc oxide to obtain aminated zinc oxide, adding aminated zinc oxide into trihydroxymethyl aminomethane solution, ultrasonically dispersing uniformly, adding dopamine hydrochloride under weak alkaline condition, stirring to obtain polydopamine-zinc oxide, adding graphene oxide into trihydroxymethyl aminomethane solution, ultrasonically dispersing uniformly, adding polydopamine-zinc oxide, reacting to obtain graphene oxide-polydopamine-zinc oxide, orderly adding epoxy resin, graphene oxide-polydopamine-zinc oxide and curing agent into acetone, and uniformly stirring. USE - The method is for preparing graphene anti-corrosion antifouling nanomaterial used for pipeline anti-corrosion coating (claimed). ADVANTAGE - The nanomaterial improves dispersibility of graphene, and improves anti-corrosion and antipollution performance of graphene.
