“…It may be due to the severe destruction of the sample’s structure, which causes severe destruction of its bonds and hinders its photoluminescence feature in contact with visible light. Therefore, despite its high transparency, the UV lamp severely destroys the ZnO nanoparticle and loses its original structure and transparency 43 .…”

This study aimed to assess the UV-shielding features of the PMMA-based thin film coatings with the addition of TiO2 and ZnO nanoparticles as nanofillers considering different contents. Furthermore, the effect of TiO2/ZnO nanohybrids at different ratios and concentrations was examined. The XRD, FTIR, SEM, and EDX analyses characterized the prepared films' functional groups, structure, and morphology. Meanwhile, the coatings' optical properties and UV-protecting capability were investigated by ultraviolet–visible (UV–Vis) spectroscopy. The UV–Vis spectroscopic study revealed that as the concentration of nanoparticles increased in the hybrid-coated PMMA, the absorption in the UVA region increased. Overall, it can be concluded that the optimal coatings for PMMA were 0.1 wt% TiO2, 0.1 wt% ZnO, and 0.025:0.025 wt% TiO2: ZnO nanohybrid. Considering the acquired FT-IR of PMMA with different content of nanoparticles before and after exposure to the UV irradiation, for some films, it was confirmed that the polymer-based thin films degraded after 720 h, with either decreasing or increasing intensity of the degraded polymer, peak shifting, and band broadening. Notably, the FTIR results were in good agreement with UV–Vis outcomes. In addition, XRD diffraction peaks demonstrated that the pure PMMA matrix and PMMA coating films did not show any characteristic peaks indicating the presence of nanoparticles. All diffraction patterns were similar with and without any nanoparticles. Therefore, it depicted the amorphous nature of polymer thin film.
