GRAPHENE ROLL-TO-ROLL TRANSFER METHOD, GRAPHENE ROLL-TO-ROLL TRANSFER APPARATUS, AND GRAPHENE ROLL

摘要

PURPOSE: A graphene roll-to-roll transfer method is provided to enable easy transfer a large-sized graphene layer on a flexible substrate through roll-to-roll etching and/or transfer process. CONSTITUTION: A graphene roll-to-roll transfer method comprises the steps of: forming a laminate(50) including a material-graphene layer-first flexible substrate from a graphene layer(20) formed on a substrate(10) and the first flexible substrate(31) contacted with the graphene layer; and removing the substrate from the laminate and transferring the graphene layer on the first flexible substrate by impregnating the laminate in an etchant(60) using a second roller part(120).
