▎ 摘　　要

NOVELTY - Preparation of graphene dispersion liquid involves preparing secondary expanded graphite from graphite, mixing the secondary expanded graphite with a dispersing agent to obtain a mixed dispersion system, and subjecting the mixed dispersion system to mechanical shearing and peeling to obtain a graphene dispersion liquid. USE - Preparation of graphene dispersion liquid (claimed). ADVANTAGE - The method enables preparation of graphene dispersion liquid with excellent dispersion effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene dispersion liquid.
