Utilization of Metal Oxides Nanoparticles in Modulating Polyvinyl Chloride Films to Resist Ultraviolet Light

Modified poly(vinyl chloride) (PVC) films with organic groups (amino group from ethylene di-amine (en) and a suitable aromatic aldehyde benzaldehyde (BEN)) were synthesized by casting using tetrahydrofuran (THF) solvent. The doped four metal oxides nanoparticles (NPs), namely: CuO, Cr2O3, TiO2, Co2O3, to improve the anti-photodegradation property. irradiated ultraviolet light resulting damage was assessed different analytical morphological techniques. These techniques included FTIR, 1H-NMR, 13C-NMR spectroscopies that used examine chemical structure, while another set of devices, namely optical microscope, scanning electronic microscopy (SEM), atomic force microscope (AFM) morphology. In order confirm modified PVC acts as photostabilizers, roughness factor (Rq) measured for films. average Rq blank PVC, PVC/CuO NPs, PVC/TiO2 PVC/Co2O3 PVC/Cr2O3 NPs 368.3, 76.1, 62.6, 53.2, 45.8, 33.8, respectively. Infrared spectroscopy weight loss determination indicated incorporated additives showed less fewer surface changes compared film. All mentioned acted UV screeners against light. film highest ability resist photo-degradation process based on results data FTIR spectra, loss, addition, after 300 h irradiation, percentage 0.911 in contrast 2.896. Among tested films, best results.
