Silver nanocomposites are widely used as photosensitive components, catalysts, Raman spectroscopy enhancement additive as well as chemical analysis, due to its a wide antibacterial spectrum, and comparatively high safety. Many researchers have been successful in developing antibacterial and disinfectant agents with silver loaded carriers. Poly(methyl methacrylate) (PMMA) is an important polymeric material with high light transmittancy, colorlessness, chemical resistance, and weathering corrosion resistance. In this study, to prepare high molecular weight (HMW) PMMA/silver nanocomposite microspheres, methyl methacrylate was suspension-polymerized using 88 mol% saponified PVA and 2,2'-azobis(2,4-dimethylvaleronitrile) as suspension agent and a low temperature initiator, respectively. The effects of polymerization conditions on the polymerization behavior and molecular structure of PMMA/silver nanocomposite microspheres were investigated in terms of initiator and suspension agent concentrations, polymerization temperature, monomer to water ratio, and agitation speed. |
