▎ 摘　　要

NOVELTY - Double-sided deposition-type roll-to-roll graphene film manufacturing device comprises a tension control unit (30) on the upper portion for depositing graphene by transferring a catalytic metal film in a roll-to-roll manner, a lower chamber (10) provided with a supply roller for supplying the catalytic metal film to the deposition chamber, a winding roller for winding the catalytic metal film on which graphene is deposited in a deposition chamber (20), deposition chamber connected to the upper portion of the lower chamber and in which graphene is deposited on the catalytic metal film, a direction changing roller for changing the direction of the catalytic metal film installed on the inner upper portion of the deposition chamber, and a tension adjusting unit for constantly adjusting the tension acting on the catalytic metal film. USE - Used as double-sided deposition-type roll-to-roll graphene film manufacturing device. ADVANTAGE - The device: prevents the damage to the catalytic metal film on which graphene is deposited; and increases productivity because the heat inside the deposition chamber can be quickly cooled through the cooling tube of the deposition chamber. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the double-sided deposition-type roll-to-roll graphene film manufacturing device.
