▎ 摘　　要

NOVELTY - Graphene nanosheet dispersion, is claimed. The graphene nanosheet has a thickness of 0.35-7 nm, and is dispersed in a solvent in the form of a single layer or multiple layers. USE - Used as graphene nanosheet dispersion. ADVANTAGE - The method: promotes the stripping of graphite during grinding and thus inhibits reaggregation of graphene nanosheets in the dispersion; and is simple and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene nanosheet dispersion, comprising (i) mixing graphite with a solid polymer, and grinding mechanically to obtain a mixed powder of graphene nanosheet/solid polymer; (ii) adding the mixed powder of graphene nanosheet/solid polymer into a solvent and dissolving the polymer to obtain an intermediate of graphene nanosheet dispersion; and (iii) removing the solid polymer dissolved in the solvent from the obtained intermediate dispersion to obtain the graphene nanosheet dispersion.
