NOVELTY - Method of transferring graphene film, involves (1) uniformly coating PMMA on a metal substrate grown with graphene by spin coating, leaving at room temperature, and heating to form a film to form a structural layer A having a PMMA/graphene/metal substrate, (2) etching the metal in the structural layer A and performing multiple cleanings to obtain a structural layer B having PMMA/graphene, (3) covering the structural layer B on a metal substrate newly grown with target graphene to form a structural layer C having a PMMA/graphene/target graphene/metal substrate, (4) etching the metal in the structural layer C and performing multiple cleanings to obtain a structural layer D having PMMA/graphene/target graphene, and (5) heating the structural layer D on the target substrate, and lifting the structural layer B from the target graphene to transfer the target graphene to the target substrate. USE - Method of transferring graphene film. ADVANTAGE - The transferred graphene film has high transfer quality, high cleanliness, excellent integrity and no organic residue.
