METHOD FOR TRANSFERRING GRAPHENE FILM
摘要:
A method for transferring a graphene film is provided. The method includes spin-coating a cera alba containing solution onto a surface of the graphene film on a metal substrate to form a cera alba layer as a supporting layer, so as to obtain a first stack having the cera alba layer, the graphene film and the metal substrate in sequence; removing the metal substrate with an etching solution to obtain a second stack having the cera alba layer and the graphene film, transferring the second stack onto a target substrate to obtain a third stack having the second stack and the target substrate, and drying the third stack; removing the cera alba layer with an organic solvent. By using natural non-toxic harmless cera alba as a supporting material, it is possible to obtain the graphene film with a clean and intact surface and low sheet resistance.
