▎ 摘　　要

NOVELTY - Preparing graphene comprises grinding graphite oxide and dispersing agent release, forming graphene oxide release from graphite oxide, dispersing on peeling dispersing agent, forming graphene oxide solid dispersion, heating graphene oxide solid dispersion to release dispersant combustion, removing release dispersant while reducing graphene oxide to graphene, where the dispersing agent is carbohydrate release and/or their derivatives. USE - The method is useful for preparing graphene (claimed). ADVANTAGE - The method has simple preparation procedure and is suitable for industrial production.
