▎ 摘  要

NOVELTY - A functionalized graphene oxide comprises graphene oxide, maleic anhydride and organic amine. The weight ratio of graphene oxide and maleic anhydride is (1-5): 1, preferably 2: 1. The organic amine is triethanolamine, diethanolamine and/or triethanolamine. USE - Functionalized graphene oxide used for graphene-based concrete resist. ADVANTAGE - The functionalized graphene oxide has concrete anti-sulfate corrosion coefficient reaching to more than 0.82, prolongs service life of concrete material, and improves economic benefit. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of functionalized graphene oxide comprising mixing graphene oxide and water, uniformly stirring, ultrasonically dispersing, adding into maleic anhydride solution, reacting, adding organic amine, reacting, filtering, repeatedly washing filter residue by water, filtering until solution is neutral and taking out filter residue; (2) functionalized graphene comprising graphene, dispersant and organic amine at weight ratio of 1: (0.5-1.0): (0.2-1), preferably 1: 0.6: 0.5; and (3) graphene-based concrete resist comprising 60-20 pts. wt. graphene carbon material, 10-50 pts. wt. alcohol amine compound, 2-8 pts. wt. inorganic salt, 1-6 pts. wt. expanding agent, 5-10 pts. wt. filler, 0.1-0.5 pt. wt. air-entraining agent and 5-50 pts. wt. water, where graphene carbon material is functionalized graphene oxide and/or functionalized graphene.
