▎ 摘　　要

NOVELTY - Graphene/carbon nanotube nano-laminated composite film comprises graphene ultra-thin film formed on water surface and carbon nanotube ultrathin film pulled out of carbon nanotube array. The weight of graphene ultrathin film in graphene/carbon nanotube nanocomposite film is less than 100%. The graphene ultrathin films and carbon nanotube ultrathin films are stacked alternately to form nano stacked structures. USE - Graphene/carbon nanotube nano-laminated composite film used for heat dissipation, electromagnetic shielding, super capacitor, lithium battery or solar battery (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of graphene/carbon nanotube nano-laminated composite film comprising pulling out aligned carbon nanotube ultrathin films from carbon nanotube arrays, stacking together carbon nanotube ultrathin film, injecting graphene dispersion into water surface to obtain graphene ultrathin film, introducing layer carbon nanotube ultrathin film in water, exporting, transferring graphene ultrathin film on water surface to the surface of carbon nanotube film, repeating, transferring layer graphene ultrathin film to layer carbon nanotube ultra-thin film to obtain graphene/carbon nanotube bilayer, coating carbon nanotube ultrathin films on graphene/carbon nanotube bilayer, transferring layer graphene ultrathin film to obtain two graphene/carbon nanotube bilayers and repeating to obtain graphene/carbon nanotube nanocomposite film.
