▎ 摘　　要

NOVELTY - Graphene dispersion, formed by graphene powder and processing solvent, where graphene in the graphene dispersion has an average diameter of 0.5-1 microm, 3-5 layers, a solid content of 5-50%, and a residue oxygen content of less than 1 wt.%, and after being left to stand for 12 hours, the graphene dispersion has a concentration distribution increasing from a top section to a bottom section in a storage container, a viscosity of 5000-8000 cps, and a graphene concentration of 20 wt.%. USE - Used as graphene dispersion. ADVANTAGE - The dispersion: has less oxygen content; meets both of environmental protection and commercialization needs with high solid content, high production yield, variation option of solvent, controllable rheology of suspension, long stable duration of suspension and reliable quality of products; and reduces manufacturing cost.
