▎ 摘　　要

NOVELTY - Preparing graphene oxide metal nanosheet composite material comprises (1) coating the graphene oxide slurry uniformly on the glass substrate, and drying it at a certain ambient temperature to form a graphene oxide film, (2) placing the glass substrate of the graphene oxide film formed in step (1) into a plasma etching machine, and performing oxygen plasma etching on the graphene oxide film to increase the surface activity of the graphene oxide film, (3) removing graphene oxide film from glass substrate, place it in a magnetron sputtering furnace, selecting a specific metal target, and performing magnetron sputtering on the surface of the graphene oxide film shot to obtain a graphene oxide metal nanoparticle composite film, (4) immersing the graphene oxide metal nanoparticle composite film in water for a period of time, and ultrasonically dispersing to obtain a graphene oxide metal nanosheet dispersion and (5) freeze-drying the graphene oxide metal nanosheet dispersion. USE - The method is useful for preparing graphene oxide metal nanosheet composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for preparing graphene oxide metal nanosheet composite material (Drawing includes non-English language text).
