▎ 摘 要
NOVELTY - Preparing two-dimensional graphene comprises (i) dispersing graphite and additives in aqueous solution to obtain mixed solution, where weight ratio between graphite and additive is 1:1 and 30:1, (ii) cyclically peeling mixture by shear to obtain suspension, (iii) allowing suspension to stand to obtain stationary supernatant and allowing to stand precipitate, and (iv) subjecting stationary supernatant to continuous centrifugal separation to obtain two-dimensional graphene suspension and nano-graphite plate which is precipitated by centrifugation. USE - The method is useful for preparing two-dimensional graphene (claimed). ADVANTAGE - The method has simple operation, controllable size, high efficiency, low cost, environmentally friendliness, and is suitable for large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for two-dimensional graphene obtained by above method.
