▎ 摘　　要

NOVELTY - Preparation of nano-silver functionalized antibacterial material involves (s1) mixing oxidized graphene solution and silver ammonia solution uniformly, stirring and reacting at 40-60℃ for period of time, adding aqueous solution of glucose, heating at 85-95℃, continuously stirring and reacting, naturally cooling, and post-processing to obtain graphene oxide/silver composite nanoparticles, and (s2) adding into methacryloylated gelatin (GelMA) solution, stirring and reacting at room temperature, and performing UV cross-linking reaction. USE - Preparation of nano-silver functionalized antibacterial material used for preparing antibacterial product (all claimed). ADVANTAGE - The prepared nano-silver functionalized oxidation graphene/methacrylate gelatin has excellent antibacterial property, and the photo-thermal antibacterial effect of the graphene oxide can be enhanced after silver nanoparticles are loaded on the oxidized graphene.
