In this work, Magnesium Oxide Nanoparticles (MgO NPs) doped with 3 g of polyvinyl alcohol (PVA) at different weight percentages (0, 2, 4, 6, and 8 wt.%) using the solvent casting method, to fabricate thin PVA-MgO nanocomposite (NC) films. These films were characterized by (i) XRD, SEM, EDX, DLS, and Zeta Potential for morphological studies, (ii) FTIR spectra and UV-Visible techniques for spectroscopic studies and (iii) DSC for thermal studies. The morphological studies showed the original structure of the MgO NPs in the PVA base matrix was kept and increased the crystallinity of the PVA- MgO NC film. SEM images confirm the presence of MgO nanoparticles with the uniform distribution of the particles on the film surface. UV-Visible spectroscopy showed the presence of MgO nanoparticles in the PVA matrix film effects on the optical and electronic properties of the polymer. With increasing MgO NP content, absorption increased in the UV region. This property is used in the preparation of UV filters for glass windows to protect our skin from solar light. With the addition of MgO NPs in PVA, optical direct and indirect bandgaps decreased from 6.17 to 5.28 eV and 5.77 to 5.03 eV, respectively, and Urbach energy (disorder) increased. The linear refractive index and extinction coefficient of these materials increased from 1.63 to 2.04 and 1.38 X 10-6 to 4.04 X 10-6, respectively. Consequently, the optical dielectric constant 𝜀r value is low and almost constant up to 5 eV (248 nm) due to insufficient photon energy, then increases. Optical conductivity greatly enhanced beyond 5 eV with increasing nanofiller weight percentage. These results reveal that the PVA-MgO nanocomposite materials are useful for UV shielding, tuneable band gap devices, photo sensors, and next-generation flexible optoelectronic devices. DSC thermal analysis of PVA-MgO NC films shows that Tg, Tc, and Tm values increased and Td values decreased with MgO nano filler weight percentage. The results demonstrate the potential of these nanocomposite materials for various applications in optoelectronics and material engineering.

Keywords: Polyvinyl Alcohol (PVA); Magnesium Oxide (MgO); Nanocomposite; UV visible Spectra; DSC.
