Claim Text:
1. An antimicrobial nanocomposite composition comprising polymerizing, by in-situ radical bulk polymerization, a first mixture of a styrene, a methyl methacrylate, and a graphene oxide; wherein the styrene and methyl methacrylate are present at a specific weight ratio of 1:1 and graphene oxide is present at 2.0 weight percent based on the weight of the styrene and methyl methacrylate, to obtain a graphene oxide polystyrene-polymethyl methacrylate (GO/PS-PMMA) composite; mixing the GO/PS-PMMA composite with hydrazine hydrate solution and a silver nitrate to form a second mixture; and treating the second mixture with microwave irradiation to obtain a reduced graphene oxide polystyrene-polymethyl methacrylate silver nanoparticle composite (R-(GO)-(PS-PMMA))AgNPs).
