▎ 摘　　要

NOVELTY - The device (100) has degassing unit (140) which is connected to metal substrate removing unit (130). The base material is dipped in the miscible fluid of the second etchant and from which metal substrate is removed by metal substrate removing unit and first graphene layer is removed. The metal substrate is dipped in the base material from which the second graphene layer is removed in the first etchant. The water unit (120) sprays water on the base material in which the second graphene layer is successively laminated. USE - Graphene manufacturing device. ADVANTAGE - The damage of the graphene layer is minimized. The usability of the graphene manufacturing device is improved. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the graphene manufacturing device. Graphene manufacturing device (100) Water unit (120) Metal substrate removing unit (130) Degassing unit (140) Cooling unit (162)
