▎ 摘  要

NOVELTY - Composite film comprises a graphene set, where the layer of the graphene is connected with a carbon nano-tube, and the interlayer bonding force between the sheet graphene is 80-150 gf. USE - Composite film for use in an electronic device (claimed). ADVANTAGE - The composite film has low expansion degree, high interlayer bonding force, not easy to be layered, and can realize batch preparation. The graphene of the functionalized carbon nano-tube can effectively improve the solid content of the slurry in the composite film, so as to improve the thickness of the single-layer film material, improve the coating efficiency of the liquid slurry, which is good for the production of batch, and improve the product yield of the graphene coiled material film. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparing the composite film; (2) an electronic device.
