▎ 摘　　要

NOVELTY - The device has multi-cone electrodes (2), a substrate (5) and a ceramic insulator (6) that are arranged in the quartz tube (4). The quartz tube is located in heating furnace (1). The substrate is connected to an electric translation table (7) and to the ground. The multi-cone electrodes are connected to the high voltage negative electricity power supply (3). USE - Device for preparing vertically oriented graphene for field emission, nano level plasma, super capacitor and secondary battery. ADVANTAGE - The vertically oriented graphene can be prepared rapidly. The graphene can be effectively produced on the surface of the substrate without using the catalyst or the adhesive. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing vertically oriented graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing vertically oriented graphene.
