▎ 摘　　要

NOVELTY - Highly concentrated graphene dispersion preparation involves dissolving graphite and dispersing agent in a polar solvent for preparing a mixture. The prepared mixture is homogenized to give the finished highly concentrated graphene dispersion. USE - Method for preparing highly concentrated graphene dispersion. ADVANTAGE - The method prepares the highly concentrated graphene dispersion in a simple and cost-effective manner on industrial scale and wide prospect value. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a high-pressure homogenizer used in highly concentrated graphene dispersion method. Collision (1) Shear stress (2) Cavitation (3)
