Abstract
The (PMMA/PVA–Mn) Nano-composites films were prepared via a photopolymerization method with different percentages (0.0%, 0.1%, and 0.2%) Of Mn with (20%PVA /80%PMMA,30%PVA/70%PMMA ad 40%PVA/60% PMMA) . The structural, bacterial, and mechanical properties of Nano-composites, were studied, X-ray properties of Mn nanoparticle which studied. Scanning electron microscopy analysis was employed to evaluate the morphological and structural properties of each thin film Nanocomposite. Moreover, the effect of Streptococcus mutans antibacterial of those materials was analyzed. Results: The morphological studies represented that both non-functionalized and Bio functionalized manganese oxide NPs (MnNPs) formed are of spherical morphology but exhibited with a difference in size about 20 nm and 27-40 nm, respectively. The performance of the antimicrobial activity. The results are revealed that the Bio functionalized MoNPs showed higher antibacterial. Results show that values increase in each of Mn Nanoparticle and with different concentrations of (PVA/PMMA) polymer, then decrease alternately less value of volume fraction of fillers. Young modules values increase alternately by the volume fraction of fillers.
