Description
Summary:ZnO nanoparticles were synthesized through a cost-effective and safe method followed by fabrication and characterization of polyethylene/ZnO nanocomposite films and investigation of their properties. The morphology and size of the synthesized nanoparticles were evaluated by field emission scanning electron microscopy (FE-SEM). It was found that nanoparticles with a plate-like morphology with an average thickness of 50-70 nm were synthesized. The nanocomposites were characterized by using Fourier transform infrared analysis (FTIR) and ultraviolet-visible spectroscopy (UV-VIS). In addition, the effects of the amount of zinc oxide nanoparticles (ZnO-NPs) on the mechanical properties of the films and particles and their antibacterial properties against a gram-negative bacterium (Escherichia coli) and gram-positive bacteria (Staphylococcus aureus) were investigated. In the case of nanoparticles, one more gram-positive bacterium (Staphylococcus aureus) was studied. The results demonstrated an inhibition of growth of all bacteria in a broth medium for both the nanoparticles and nanocomposites. The FE-SEM micrographs revealed that by increasing the nanofiller content an inferior quality of dispersion was obtained which was reflected in the lower tensile strength of the nanocomposites compared to the pure PE. It was demonstrated that the addition of poly ethylene graft maleic anhydride (PE-g-MA), as compatibiliser, improved the dispersion state of the nanoparticles and, consequently, the ultimate mechanical properties. In addition, it was shown that the fabricated nanocomposites exhibited considerable UV-shielding properties.
