Beschreibung
Zusammenfassung:	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. L'invention concerne des nanocomposites de copolymère de styrène et de méthacrylate de méthyle contenant des nanoparticules réduites d'argent/d'oxyde de graphène (PS-PMMA/RGO/AgNPs), préparés grâce à un procédé de polymérisation en vrac in situ en utilisant deux techniques de préparation différentes. Lors de la première approche, un mélange d'oxyde de graphène (GO), de monomères de styrène (S) et de méthacrylate de méthyle (MMA) a été polymérisé à l'aide d'un procédé de polymérisation en vrac avec un initiateur de radicaux libres. Après l'addition de nitrate d'argent (AgNO3), le produit a été réduit par l'intermédiaire d'une irradiation aux micro-ondes (MWI) en présence de l'agent réducteur hydrate d'hydrazine (HH) afin d'obtenir le nanocomposite R-(GO-(PS-PMMA))/AgNPs. Ce nanocomposite a été ensuite utilisé pour créer un matériau qui avait des propriétés antimicrobiennes, destiné à être utilisé dans des dispositifs médicaux ou des implants médicaux.
