▎ 摘　　要

NOVELTY - Graphite is quadratic expanded, to obtain quadratic-expanded graphite. Quadratic-expanded graphite and dispersant in mass ratio of 5:1-1:5 are mixed, to obtain mixed dispersion. The mixed dispersion is subjected to mechanical shear, to obtain graphene dispersion. USE - Preparation of graphene dispersion (claimed). ADVANTAGE - The method enables preparation of graphene dispersion having excellent dispersion characteristics.
