چکیده
|
Polymethylmethacrylate-silver (pmma/ag) nanocomposite is synthesized by irradiating thesolution of silver ions in methylrnethacryl ate monomer by y-ray. in this method, polymerization of themethylmethacry late monomer and the silver ion reduction occurred simultaneously. optical properti es ofthe pmmnag solutions are investigated using uv-vis spectroscopy. the structural characterizations ofthe pmma/ag nanocomposite are determined by ftir spectroscopy xrd, and sem measurements. thesem image shows that the ag nanoparticles disperse in the pmma matrix with a relatively uniformdistr ibution. the antibacterial studies show that the pmmaiag nanocomposite is antibacterial against e.coli, as a model for gram-negative bacteria
