Abstract

The invention relates to the production of carbon nanomaterials, for example graphene, and can be used to produce graphene for use in nanoelectronics. Graphene is produced by stratifying graphite particles, differing in that graphite particles undergo electrodynamic fluidization in a vacuum in which the energy of the graphite particles exceeds the work necessary for their cleavage along the cleavage planes on graphene layers during brittle fracture when striking against the electrodes. The method makes it possible to obtain graphene with high productivity, economy and purity of the product.

Claims (1)

1. A method for producing graphene by graphite stratification, characterized in that the graphite particles are subjected to electrodynamic fluidization in a vacuum in which the energy of the graphite particles exceeds the work necessary to split them upon impact of particles on the electrodes.
