▎ 摘　　要

NOVELTY - Large area graphene preparation device comprises a mainframe part i.e. mounted on the upper part of the main machine part, where one side is connected with the gas inlet, the box furnace (chamber) can be connected with the vacuum unit on the other side, the 1 heater is installed at the upper part of the furnace (chamber), the 1 heater driving unit is can adjust the second heater 1 and the relative position of the furnace (chamber), the 2 heater is installed at the lower part of the furnace (chamber), and the 2 heater driving unit can adjust the first heater 2 and the relative position of the furnace (chamber). USE - Used as large area graphene preparation device. ADVANTAGE - The device: adopts the heater driving unit to adjust the relative position of the first heater and the chamber; can installs the first heater drive unit on the lower part of the chamber 2 heaters; and adopts second heater driving to adjust a relative position of the second heater and the chamber. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of large area graphene preparation device.
