▎ 摘　　要

NOVELTY - Production of graphene involves applying physical force to liquid dispersion of dispersing agent and carbon-based material comprising graphite or its derivative, and forming graphite or its derivative into nano graphene flakes by applying physical force. The dispersing agent is mixture of different types of 60 wt.% or more polyaromatic hydrocarbon oxide having molecular weight of 300-1000. USE - Production of graphene (claimed). ADVANTAGE - The method enables easy production of thin graphene having high surface area.
