▎ 摘  要

NOVELTY - A graphene transfer method involves: attaching a first end of a first stacked structure (310) including catalyst metal, graphene and supporting body, to a point of a target film that is transported in a roll-to-roll manner in a first direction; forming a second stacked structure (320) by removing the catalyst metal of the first structure, where the second structure having a surface on which the graphene is exposed; and transferring the exposed graphene to a transfer surface of target film by transporting film in a roll-to-roll manner and second structure in first direction. USE - As a graphene transfer method (claimed). ADVANTAGE - The present method achieves removal of supporting body by using an organic solvent (such as acetone) without applying predetermined heat and pressure. Thus the present method prevents damage to the graphene, and deterioration of electric properties of graphene, as compared to the related art. DETAILED DESCRIPTION - A graphene transfer method involves: attaching a first end of a first stacked structure (310), including a catalyst metal, graphene, and a supporting body stacked in the order stated, to a point of a target film that is transported in a roll-to-roll manner in a first direction; forming a second stacked structure (320) by removing the catalyst metal of the first stacked structure, where the second structure having a surface on which the graphene is exposed; and transferring the exposed graphene to a transfer surface of the target film by transporting the target film in a roll-to-roll manner and the second stacked structure in the first direction. The catalyst metal is removed via a wet-etching process by floating the first stacked structure at surface level in a catalyst metal removing liquid (201). The wet-etching process is performed by using components (c1). The method further involves: after the transferring of the graphene, transporting the target film in a roll-to-roll manner and the second stacked structure in a direction opposite to the first direction and cleaning the graphene transferred to the target film by floating the graphene on the surface of a cleaning liquid; and transferring the cleaned graphene back to the transfer surface of the target film by transporting the target film in a roll-to-roll manner and the second stacked structure in the first direction. A container (200) is filled with the catalyst metal removing liquid after the catalyst metal is removed, and the catalyst metal removing liquid is discharged from the container and the container is filled with the cleaning liquid before the cleaning of the graphene. The method further involves: after the transferring of the graphene, removing the supporting body by using a supporting body removing liquid. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a graphene transfer method.
