▎ 摘　　要

NOVELTY - Preparing graphene aqueous stable dispersion liquid, comprises (i) taking dispersant, adding water, magnetic stirring for 2-3 minutes, and dispersing uniformly, where the mass to volume ratio of dispersant and water is 0.5-5:10-100 g/ml; and (ii) adding graphene into the dispersion liquid, where the mass to volume ratio graphene and dispersion liquid is 0.1:10-100 g/ml, magnetic stirring for 2-3 minutes, ultrasonic dispersing for 1-10 hours to obtain highly dispersed stable graphene aqueous dispersion liquid. USE - The method is useful for preparing graphene aqueous stable dispersion liquid (claimed). ADVANTAGE - The method does not cause loss of physical and chemical properties of graphene and is environmentally friendly.
