Graphene transfer method |
摘要 |
A graphene transfer method comprising: attaching a first end of a first stacked structure, 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 by removing the catalyst metal of the first stacked structure, the second stacked structure having a surface whereon 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. |

1. A graphene transfer method comprising:
attaching a first end of a first stacked structure, 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 by removing the catalyst metal of the first stacked structure, the second stacked structure having a surface whereon 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, wherein 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, and wherein the method further comprises: 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. |
