NOVELTY - Modified graphene composite slurry comprises 1-40 pts. wt. expanded graphite, 0.01-10 pts. wt. first dispersant, 0.01-4 pts. wt. first defoamer, 40-99 pts. wt. first solvent, dispersants, rheology additives, defoamers, second solvents and solvents. USE - Modified graphene composite slurry. ADVANTAGE - The modified graphene composite slurry more effectively solves the dispersion difficulties of graphene in downstream applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing modified graphene composite slurry, which involves: (A) grinding and mixing expanded graphite, the first dispersant, the first antifoaming agent and the first solvent to obtain the mixed solution; (B) using a second solvent to perform hot filtration and cleaning on the mixed solution; (C) obtaining modified graphene solution; and (D) grinding and mixing modified graphene, dispersant, rheology aid, defoamer and solvent to obtain modified graphene composite slurry.
