  • Method and device for production of graphene or graphene-like materials
    Patent number: 10843145
    Abstract: A method and a device for the production of graphene or graphene-like material are provided. The method can comprise the following steps: providing particles of a crystalline graphitic material; dispersing the particles in a solvent or surfactant mixture; submitting the mixture to a cavitation force such that cavitation bubbles are present; and submitting the mixture to high shear agitation. The cavitation and high shear agitation steps can be simultaneous, in particular in the same enclosed vessel. The device for the production of graphene or graphene-like material can comprise a reactor having an enclosed vessel for receiving a solvent or surfactant mixture with dispersed particles of a crystalline graphitic material. The reactor can be arranged for: submitting the mixture in the enclosed vessel to a cavitation force such that cavitation bubbles are present and, simultaneously in the same enclosed vessel, submitting the mixture to high shear agitation.
