Graphene, graphite nanosheets and preparation method

The invention relates to a mechanochemical method. The mechanochemical method comprises the following step: subjecting natural graphite and synthetic graphite to fine crushing and stripping so as to obtain graphite nanosheets, and even monolayer graphite nanosheets. The graphite nanosheets and the monolayer graphite nanosheets are a novel functional carbon material with high electrical conductivity and high thermal conductivity, can be compounded with organic macromolecules and inorganic materials, and have extensive applications in the fields of electronics, luminescence, batteries, buildingmaterials, decoration, daily use, etc. 本发明涉及用力化学法对天然石墨和合成石墨进行精细化粉碎和剥离，得到纳米石墨片、甚至得到寡层纳米石墨烯片。所得的纳米石墨片和寡层纳米石墨烯片是种高导电、高导热的新型功能性碳材料，既可与有机高分子复合、也可与无机材料复合，在电子、发光、电池、建材、装饰、日用等领域有广泛的用途。
