▎ 摘　　要

NOVELTY - The device has a furnace portion (1). The top end of the furnace portion is rotatably connected with a furnace cover (20). Two sides of furnace portion are welded with a supporting frame (2). The supporting frame is provided with furnace tube (3). A side of furnace tube is installed with a sealing sleeve (4) through a flange. The sealing sleeve is fixedly installed with a motor (5). An output end of motor is screwed with a connector far away from the motor. The one side of connector is connected with quartz tube. The quartz tube is covered with a metal film. USE - Preparation device of graphene. Uses include but are not limited to mechanical stripping method, oxidation-reduction method, silicon carbide epitaxial growth method and chemical vapor deposition method. ADVANTAGE - The metal film on the quartz tube follows the rotation, so that the metal film is uniformly heated to generate graphene, so as to improve the graphene of the yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphite alkene. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a preparation device of graphene. 1Furnace portion 2Support frame 3Furnace tube 4Sealing sleeve 5Motor 20Furnace cover
