▎ 摘　　要

NOVELTY - Device for preparing graphene comprises graphite rod (1) as a negative electrode, graphite cylinder (2) as a positive electrode, crucible (3), induction coil (4) and water tank (5), where graphite rod is suspended in a graphite cylinder and the graphite cylinder (2) is suspended in a ceramic crucible. The induction coil is arranged around the graphite cylinder and a high-frequency induction coil is wound around the ceramic crucible. The water tank is provided with cooling water. USE - Device for preparing graphene. ADVANTAGE - The device for preparing graphene is eco-friendly, simple and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for graphene preparation, which involves: (A) adding the electrolytic solution to the ceramic crucible and applying a voltage of 5-10 volt between the graphite rod and the graphite cylinder; (B) energizing graphite cylinder and ceramic crucible to generate an electromagnetic field, so that the graphite cylinder surface is induced; and (C) peeling the graphene from the surface of the graphite cylinder by the interaction of the electric field and the magnetic field on the surface of the graphite cylinder. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of device for preparing graphene Graphite rod (1) Graphite cylinder (2) Crucible (3) Induction coil (4) Water tank (5)
