Abstract
The preparation of graphene, mono-, bi- and multi-layers from graphite-based precursor materials, for example, pencil lead or graphite, by a method of mechanical thinning on the surface of a planar substrate with controlled roughness, followed by sonication in order to collect the graphene deposited on the substrate in a liquid medium. The bearing force during thinning by mechanical friction enables the number of graphene sheets deposited on the surface of the substrate to be controlled.
