▎ 摘 要
NOVELTY - Fabricating graphene platelet comprises (A) providing a highly-graphitized graphene having a graphitization degree of 0.8-1, and (B) providing a shear force acting on the highly-graphitized graphene to separate the highly-graphitized graphene into graphene platelets having a length of 10-500 mu m, a width of 10-500 mu m and a single-layer or multi-layer structure. USE - The method is useful for fabricating graphene platelet (claimed). ADVANTAGE - The method is capable of efficiently fabricating large-area graphene platelet with superior stability, thermal conductivity and physical properties.
