Antioxidation Effect of Graphene Oxide on Silver Nanoparticles and Its Use in Antibacterial Applications

Silver nanoparticles (AgNPs) have drawn great attention due to their outstanding antibacterial effect in a wide range of applications, such as biomass packaging materials, wound dressings, flexible sensors, etc. However, the oxidation AgNPs limits effect. Firstly, effects pretreatment methods on property were investigated by shake flask method and agar diffusion plate method. Secondly, graphene oxide/silver nanoparticle (GO/AgNPs) nanocomposite prepared an in-situ growth was used filler for polyacrylate emulsion via blending The mechanism GO/AgNPs revealed comparing actual contents oxygen with theoretically calculated oxygen. Finally, polyacrylate/graphene (PA/GO/AgNPs) composite applied onto leather surface using layer-by-layer spraying improve leather’s properties. results showed that ultraviolet irradiation could better maintain AgNPs, while GO dispersibility prevent oxidation. finished PA/GO/AgNPs-2 wt% highest bacteriostatic rate 74%, demonstrating its potential application products.
