▎ 摘　　要

NOVELTY - A graphene film is used by spin coating high polymer protection film on surface of graphene film; peeling off from substrate by rinsing with de-ionized water; transferring film to surface of polymer sponge structure; and drying the polymer sponge structure, removing water from surface of graphene-polymer film to obtain floating graphene-polymer polymer film in deionized water. USE - Method for application of graphene film (claimed). ADVANTAGE - The method is simple, reliable, low cost, and convenient.
