▎ 摘　　要

NOVELTY - Preparation of graphene oxide/silver nanocomposite hybrid antibacterial material involves adjusting the pH of the graphene oxide aqueous solution to alkaline with a strong alkali solution, adding epichlorohydrin to alkaline graphene oxide aqueous solution, stirring and reacting at 50-70 degrees C for 2-5 hours, after cooling, using deionized water for centrifugal washing 3-5 times to obtain epichlorohydrin-modified graphene oxide, dispersing epichlorohydrin-modified graphene oxide in the carbonate buffer solution at a concentration of 0.3-3 g/l, mixing the amino-terminated hyperbranched polymer solution with the silver nitrate solution and heating it to boiling for 3-5 minutes, adding the amino-terminated hyperbranched polymer nano-silver solution to the epichlorohydrin modified graphene oxide solution, stirring, and reacting at 50-70 degrees C for 2-5 hours. USE - Preparation of graphene oxide/silver nanocomposite hybrid antibacterial material used for functionalizing fiber or fabric product (claimed). ADVANTAGE - The method is simple, and enables preparation of graphene oxide/silver nanocomposite hybrid antibacterial material.
