▎ 摘　　要

NOVELTY - The method comprises binding a planar target substrate of graphene layer to a primary substrate using a binding force or a bonding layer, separating the primary substrate, graphene layer or target substrate and target substrate, graphene, bonding layer or target substrate, placing electrodes as an electrolyte solution on the primary substrate, performing an electrolysis method to generate gas bubbles on a surface of the substrate using a pushing force, and separating primary substrate and graphene using the gas bubbles. USE - The method is useful for transferring large-area graphene to a substrate (claimed). ADVANTAGE - The method is capable of simply, continuously and economically transferring high quality graphene to the substrate without any damage to graphene in an eco-friendly manner. DETAILED DESCRIPTION - The method comprises binding a planar target substrate of graphene layer to a primary substrate using a binding force or a bonding layer, separating the primary substrate, graphene layer or target substrate and target substrate, graphene, bonding layer or target substrate, placing electrodes as an electrolyte solution on the primary substrate, performing an electrolysis method to generate gas bubbles on a surface of the substrate using a pushing force, and separating primary substrate and graphene using the gas bubbles. The graphene layer is formed on the substrate by chemical vapor deposition method or graphene precipitation method. The binding step is carried out using the force or binding layer without any breakage during the operation. The binding layer is formed on a surface of graphene layer or a surface of target substrate. The binding force includes electrostatic forces, van der Waals forces, covalent bonding force, hydrogen bonding force, vacuum suction force, or a mechanical coupling force. The binding layer includes layers of adhesives and azide and self-assembled monolayers. The adhesive layer has a thickness of 50 nm to 1 mm. The self-assembled monolayers include chain molecule, macrocyclic plane conjugated molecules and macromolecules of biological samples. The binding step is carried out using a roll-to-roll rolling method. The electrolyte solution has a concentration of 0.01-10 mol/l. The electrolysis method is performed at 10-100?OC, a voltage of 1-100 V and a current of 0.01-100 to generate hydrogen, oxygen or chlorine.
