Method for Preparing Graphenes

The invention relates to a method for manufacturing a dispersion of graphene particles or flakes, including the following steps: (a) providing a carbon material; (b) dispersing said material in an aqueous or organic liquid so as to obtain a dispersion; (c) microwave heating said dispersion so as to obtain a dispersion containing graphene particles or flakes and carbon raw materials; and (d) separating said graphene dispersion from said carbon raw material so as to obtain a dispersion of graphene particles or flakes. The graphene particles can be isolated by filtering or centrifuging, or by evaporating the solvent.
