▎ 摘　　要

NOVELTY - Method for preparing graphite alkene, involves (a) mixing nano-carbon ball, graphite and water to prepare pretreated nano carbon ball/graphite dispersion liquid, (b) peeling the pretreated nano fibril ball and graphite dispersive liquid to obtain graphene dispersion solution, and (c) freezing dispersion fluid and freezing graphene dispersive solution to obtain final product. USE - Preparation method of graphene. ADVANTAGE - The method enables to prepare graphene, which has a layer number of 1-10 layers, and the transverse size is 0.5-10 microns. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for liquid-phase stripping system for preparing graphene.
