This study investigates the effect of incorporating silver oxide (AgO) nanoparticles into a polymer composite made of polyvinyl alcohol (PVA) and carboxymethyl cellulose (CMC) were mixed in a 1:1 ratio. Nanocomposite films were prepared using casting method process with adding different concentrations of AgO nanoparticles (0.3, 0.5 and 0.7 wt%). Structural properties, Fourier-transform infrared (FTIR) and scanning electron microscope (SEM) analyzes were used to evaluate the effect of AgO incorporation on the properties of the polymer blend. Samples’ optical properties were tested by measuring their UV-Visible spectra. The findings show that the addition of AgO nanoparticles significantly improves the structural and optical properties of the mixture. For the nanocomposites containing 0.3, 0.5, and 0.7 wt% AgO, the optical band gap gradually decreased from 5.35 eV (pure mixture) to 5.25, 5.20, and 5.16 eV, respectively.
