Synthesis of Ag/PMMA nanocomposite by gamma irradiation

Silver/Polymethylmethacrylate (Ag/PMMA) nanocomposite was synthesized in a facile procedure byγ-irradiation of the solution containing silver ions and methylmethacrylate monomer. In this method, polymerization of the monomer and formation of silver nanoparticles were occurred simultaneously. Optical properties of the Ag/PMMA were investigated using UV-Vis spectroscopy. Structural characterizations of the Ag/PMMA nanocomposite were determined by FTIR spectroscopy XRD, and SEM analysThe SEM image showed that the Ag nanoparticles with a mean diameter of about 90 nm were dispersed in PMMA matrix with a relatively uniform distribution. The antibacterial studies showed that the Ag/PMMA nanocomposite was antibacterial against E.coli,as a model of gram-negative bacteria.
