▎ 摘 要
NOVELTY - High gravity preparation of graphene, comprises (i) pre-treating graphite raw material, so that the graphite layer spacing increases, to obtain pre-treated graphite; (ii) peeling the pre-treated graphite in a high gravity rotating bed. USE - The method is useful for high gravity preparation of graphene (claimed). ADVANTAGE - The preparation method is simple, easy and economical, produces high yield, is suitable for large scale production. The graphene has high conductivity and little defect.
