Abstract :
Herein, polyvinyl butyral (PVB) films were synthesized using casting method and added to the PVB solution to make composites of PVB-nanoparticles were made via mixing 0.001 wt/wt % each time of each of the following metal nanoparticles (CuO, Cr2O3, NiO, TiO2 and Co3O4(NPs)) with PVB solution at room temperature. The PVB-NP composites as films were irradiated with UV light for prolonged period which demonstrated spectral, and weight-loss changes. Those changes were much more significant than that of the blank PVB films undergo under identical conditions. Incorporating surface morphology examination of the composites were conducted using scanning electron microscopy (SEM), energy x-ray dispersive (EDX) spectroscopy and atomic force microscope. Overall, findings revealed that PVB-(CuO, Cr2O3, NiO, TiO2 and Co3O4) NP composites showed a higher weight loss in compared to the PVB blank suggestive of higher photodegradation of the PVB-NP composites compared to the neat PVB film. A proposed photodegradation mechanism will be discussed.
