 This study assessed the UV shielding capabilities of PMMA-based thin films with the addition of TiO2 and ZNO nanoparticles as nanofillers. It was found that the addition of these nanoparticles improved the UV shielding capabilities of the films, with the best performance achieved when the ratio of TiO2 to ZNO was 0.025 to 0.025. Additionally, the FTIR analysis showed that the polymer-based thin films degraded over time, with either decreased or increased intensity of the degraded polymer, peak shift, and band broadening. The XRD analysis also indicated that the pure PMMA matrix and PMMA coating films did not show any characteristic peaks indicating the presence of nanoparticles.
