▎ 摘　　要

NOVELTY - Transferring graphene thin film comprises covering the molten paraffin on the surface of the graphene film formed on the surface of the growth substrate, after solidifying the paraffin, removing the growth substrate and obtaining paraffin/graphene composite film, setting the paraffin/graphene composite film on the surface of the target substrate to make the graphene film contact with the target substrate, heating the target substrate until the paraffin attached on the target substrate, using a solvent to remove the paraffin. USE - The method is useful for Transferring graphene thin film (claimed). ADVANTAGE - The method adopts paraffin as the transfer medium, is convenient for operation, and can realize an essentially lossless transferring the graphene film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing sensor comprising using graphene film surface channel electrode into touch control sensor of the graphene thin film pattern, on the surface of the graphene film of patterned optical cement package and deaeration treatment.
