NOVELTY - Colloidal graphene aqueous slurry comprises 0.1-8 wt.% graphene, 0.1-5 wt.% wetting agent, 0.05-2 wt.% surfactant, 3-6 wt.% stabilizer and 79-96.75 wt.% deionized water. USE - Colloidal graphene aqueous slurry. ADVANTAGE - The colloidal graphene aqueous slurry has excellent performance, synergistic effect of high molecular polyvinyl alcohol on the graphene, avoids the graphene again overlapped to form graphite, has very strong repulsive interaction, so that the graphene is stably suspended in water, and also has low viscosity, and excellent stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing colloidal graphene aqueous slurry, which involves: (A) dispersing the wetting agent in deionized water to form a wetting solution; (B) adding the graphene powder to the wetting solution and stirring uniformly, and transferring to a sand mill to obtain preliminary dispersed graphene aqueous solution; and (C) adding a surfactant to the graphene aqueous solution and stirring well and adding stabilizer is added to the graphene aqueous solution and stirred to obtain desired product.
