| dc.description.abstract | This thesis presented the development of polymer/ aluminum (al)-silver (ag)-zinc oxide (zno) nanocomposites (ncs) with single-metal (al, ag, or zno) or bimetallic (al+ag), (al+zno), and (ag+zno) configurations for ultraviolet (uv)-shielding applications. The casting technique was employed for the fabrication of flexible foil-shaped (al-ag-zno), (al+ag), (al+zno), and (ag+zno) nanoparticles (nps). The (al-ag-zno) nps added as filler at 0, 1, 5, 10, and 15 wt%, while (al+ag), (al+zno), and (ag+zno) with 5 wt% to polymer matrices such as polyvinyl alcohol (pva), polymethyl methacrylate (pmma), and polystyrene (ps). The morphology of al, ag, and zno nps, with a size range of 20 to 160 nm, was analyzed using the transmission electron microscopy (tem) technique. Energy dispersive x-ray (edx) examination showed the presence of al, ag, and zno nps in the samples at different concentrations, confirming their dispersion inside the polymer matrix. Uv-visible transmittance spectra showed low transmittance in the uv range, with a contrasting trend observed relative to nps concentrations. Uv-visible absorption spectra showed high absorption in the uv region, which was inversely related to the presence of (al+ag), (al+zno), and (ag+zno) ncs. | |
