This study is concerned to the immobilization of silver-loaded titanium dioxide (AT) nanoparticles (NPs) into or onto
polyvinyl alcohol (PVA) as matrix. The nanocomposites films were fabricated via solution casting method. The optical
properties and morphology of the NPs and nanocomposites were characterized by dynamic light scattering, transmission
electron microscopy, fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, contact angle measurements, field emission scanning electron microscopy (FE-SEM), and atomic force microscopy (AFM). The obtained
results of FE-SEM analysis for nanocomposites indicate that the 40–80 nm AT NPs are homogenously distributed in
PVA matrix. The unsymmetrical parts of peaks and valleys for nanocomposites in three-dimensional AFM images were
related to the residual of AT NPs in outsides, although in the majority of locations it showed similar patterns of peaks
and valleys. The studies of nanocomposites by using UV revealed that existence of the AT NPs were increased the shield
properties against UV light. Reinforcement of PVA with AT nanomaterials enhances the properties of the prepared films
and develops their applications in different industrial fields such as packaging.
