▎ 摘　　要

NOVELTY - Preparing graphene antibacterial composite film involves adding silver nitrate powder to the graphene oxide aqueous solution and ultrasonically to obtain a graphene oxide/silver nitrate composite material, dispersing the graphene oxide/silver nitrate composite material on the bacterial cellulose membrane to obtain a bacterial cellulose/graphene oxide/silver nitrate composite membrane, treating bacterial cellulose/graphene oxide/silver nitrate composite membrane with plasma in an inert protective gas, washing with deionized water, and natural drying, and obtaining graphene antibacterial composite membrane. USE - Method for preparing graphene antibacterial composite film. ADVANTAGE - The method has simple reaction, mild conditions and rapid preparation, has strong stability and does not require other treatments, and is ready to use.
