▎ 摘　　要

NOVELTY - Graphene nanoribbon composite film preparation involves infiltrating graphene sheet into surface of composite film by a dispersion solvent, and then dissolving in dispersion solution for forming glue together with the dispersion solution. The dispersion solvent is internally provided with a polymer binder. USE - Method for preparing graphene nanoribbon composite film used in energy storage, liquid crystal device, electronic device, biological material, and catalyst carriers. ADVANTAGE - The method prepares the graphene nanoribbon composite film in a simple, cost-effective and eco-friendly manner with characteristics of high conductivity, high strength, ultra-lightness, very stable overall structure, and very small internal electrons.
