Photostabilizing polymeric materials is crucial for protecting them from damage by UV irradiation. Recent advancements have significantly enhanced polymer resistance to photooxidation and harsh environmental conditions by developing polymeric additives designed to act as photostabilizers. The present study assesses the significant impact of metal oxide nanoparticles (NPs) on enhancing the surface properties of poly(methyl methacrylate) (PMMA) and paving the way for more durable applications. The reaction of PMMA and propylenediamine led to the incorporation of amino residues, which was followed by the attachment of various metal oxide NPs, namely nickel oxide (NiO), titanium dioxide (TiO2), magnesium oxide (MgO), and zinc oxide (ZnO). Thin PMMA films doped with metal oxide NPs experienced reduced photodegradation compared to PMMA films containing the amino residues only. Of the metal oxide NPs studied, PMMA doped with ZnO NPs exhibited the lowest level of weight loss and surface damage caused by UV irradiation. These findings indicate the potential of metal oxide NPs in enhancing the photostability and surface properties of PMMA, contributing to the development of more durable polymeric materials.
