▎ 摘　　要

NOVELTY - Preparing graphene aqueous dispersion liquid comprises adding amino graphene quantum dot powder as dispersant into graphene pre-wetting liquid, and dispersing uniformly to obtain final product. USE - The method is useful for preparing graphene aqueous dispersion liquid which is useful in anti-corrosive paint. No biological data given. ADVANTAGE - The method enables to prepare graphene aqueous dispersion liquid that has good dispersibility of graphene, and does not introduce non-graphene impurity in the dispersion, so as to well store the graphene nano-characteristics in the anti-corrosive paint. DESCRIPTION OF DRAWING(S) - The drawing shows the invention prepared in the graphene aqueous dispersion after standing shape.
