▎ 摘　　要

NOVELTY - Graphene dispersion comprises graphene, a dispersant and water. The dispersant is chosen from anionic surfactant, cationic surfactant and nonionic surfactant. USE - As graphene dispersion. ADVANTAGE - The graphene dispersion adopts a simple preparation process and has excellent monodispersity and high storage stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the graphene dispersion involving providing a graphene dispersion composition and treating the composition by a dispersion device to obtain the graphene dispersion, where the composition comprises graphene, the dispersant and water and the dispersion device is chosen from an ultrasonic cell crusher, a high-pressure homogenizer, a sand mill, a ball mill and a high-speed shear emulsifier.
