▎ 摘　　要

NOVELTY - The film is an asymmetric thin film. The inner portion of the graphene oxide film is provided with a slit shaped flexible hole. The hole diameter of the hole is 0.1 microns to 10 microns. The graphene oxide film is obtained by high vacuum evaporation coating method of evaporation. The graphene oxide/metal bilayer films are obtained. USE - Electrically actuated graphene oxide/metal bilayer film. ADVANTAGE - The preparation process of film is convenient and rapid. The electric actuation graphene oxide/metal bilayer films ensures excellent electrochemical stability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrically actuated graphene oxide/metal bilayer film.
