    This study synthesized PVC films modified with organic groups, such as amino groups from propylene diamine, and metal oxides in two steps. THF solvent was used to cast the films. The films were infused with nanoparticles of ZnO, TiO₂, MgO, and NiO to resist photodegradation. After applying UV radiation to these films, analytical and morphological methods were used to assess the expected damage. Fourier-transform infrared (FTIR) spectroscopy identified the chemical structure, while atomic force microscopy and scanning electron microscopy examined the film shape. We measured radiation-exposed plain and modified films' roughness factor (R<sub>q</sub>) to determine photostabilization efficacy. After irradiation, plain PVC, chemically modified PVC, and filled PVC films with ZnO, TiO₂, MgO, and NiO nanoparticles had mean Rq values of 245.3, 122.1, 87.1, 66.4, 51.8, and 40.2. Weight loss and infrared spectroscopy showed that films with additives had fewer surface damages than those without. All metallic fillers blocked UV. In all samples, modified PVC/NiO NP film mitigated photodegradation best. FTIR spectra, weight loss, and surface morphology determined this.
