METHOD FOR TRANSFERRING GRAPHENE FILM USING ELECTROSTATIC PROTECTION FILM AS MEDIUM

摘要

The present invention relates to a method for transferring a graphene film using an electrostatic protection film as a medium. The method comprises: using the electrostatic adsorption of an electrostatic protection film to adhere a graphene comprising a growth substrate, then removing the growth substrate to obtain a graphene/electrostatic protection film combination, and finally, adhering the single-layer graphene/electrostatic protection film combination to a target substrate and releasing static electricity to remove the electrostatic protection film to obtain a single-layer graphene film; alternatively, after the single-layer graphene/electrostatic protection film combination is obtained, replacing the electrostatic protection film with the single-layer graphene/electrostatic protection film combination, and on a new graphene comprising a growth substrate, repeatedly adhering the graphene/electrostatic protection film and removing the growth substrate in sequence, so as finally to obtain a multilayer graphene film. The method has a simple and convenient operation, has no residue of glue and does not need an organic solvent to conduct subsequent cleaning, thereby reducing the process costs for transferring a graphene film.
