  • Antimicrobial polymer-graphene-silver nanocomposite
    Patent number: 9334386
    Abstract: The copolymer of styrene and methylmethacrylate containing reduced graphene oxide/silver nanoparticles (PS-PMMA/RGO/AgNPs) nanocomposite were prepared via in situ bulk polymerization method using two different preparation techniques. In the first approach, a mixture of graphene oxide (GO), styrene (S) and methylmethacrylate monomers (MMA) were polymerized using a bulk polymerization method with a free radical initiator. After the addition silver nitrate (AgNO3), the product was reduced via microwave irradiation (MWI) in presence of the reducing agent hydrazine hydrate (HH), to obtain R-(GO-(PS-PMMA))/AgNPs nanocomposite. This nanocomposite was then used to create a material that had antimicrobial properties to be used in medical devices or medical related implants.
