Abstract

The invention relates to a method for transferring a graphene film with a static protective film as a medium. The method includes that the static protective film is attached to graphene containing a growing lining through an electrostatic adsorption effect, then the growing lining is removed, a graphene / static protective film combination is obtained, finally a single layer of the graphene / static protective film combination is attached to a target substrate, static is released, the static protective film is removed, and the single-layer graphene film is obtained; or after the single layer of the graphene / static protective film combination is obtained, the single-layer of the graphene / static protective film combination replaces the static protective film, attaching of the graphene / static protective film is conducted sequentially on the graphene containing the growing lining repeatedly, the growing lining is removed, and finally a plurality of layers of graphene films are obtained. The method is simple to operate and free of residual glue, and organic solvent for following washing is not required, and therefore process cost for transferring the graphene films is reduced.

Description

technical field [0001] The invention relates to a method for transferring a graphene film, in particular to a method for transferring a single-layer or multi-layer graphene film using an electrostatic protective film as a medium, and belongs to the field of conductive film materials. Background technique [0002] Graphene thin films have high light transmittance and extremely high carrier mobility, and have great application prospects in electronic devices and solar cells. In order to fabricate graphene electronic devices, the primary problem is to prepare large-scale graphene films and transfer them to suitable target substrates. [0003] The transfer technology of graphene film is a method of transferring graphene between different substrates, usually transferring graphene from a growth substrate to a target substrate. The transfer technology of graphene film is the key factor restricting the development of graphene film. The ideal transfer technology should have the foll...
