▎ 摘　　要

NOVELTY - Dispersing graphene comprises using the hard material particles in the vibration fluidized and irregular motion state, using the graphene oxide solution, uniformly spraying on the surface of hard material particles to obtain the composite material with uniformly dispersed graphene. USE - The method is useful for dispersing graphene (claimed). ADVANTAGE - The method effectively solves the problem that the graphene is easy to agglomeration, can ensure the uniformly dispersed graphene to better exert its good performance, and is more widely applied. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene composite material comprising hard material particles and the surface uniformly dispersed composite of graphene layer, the grain size of the hard material particles is 10-5000 meshes.
