description The invention relates to a method for nondestructively transferring a graphene thin film in a large area. The method comprises the following steps: (1) aligning and attaching the both surfaces of a metal substrate on which a graphene thin film grows to a transfer medium, and carrying out roll pressing by using a rolling press to obtain a transfer medium/graphene thin film/metal substrate/graphene thin film/transfer medium laminar material; (2) with the laminar material obtained in the step (1) as a positive electrode and a platinum electrode as a negative electrode, inserting into an electrolytic cell, applying a direct voltage, putting the transfer medium/graphene thin film into corrosive liquid after the transfer medium/graphene thin film is completely peeled from the metal substrate, etching the residual metal on the surface of the graphene thin film, then rinsing with distilled water, and drying by blowing; and (3) attaching the transfer medium/graphene thin film to a target substrate, and carrying out ro
