Using polyvinyl chloride (PVC) and SiO2 NPs in Tetrahydrofuran (THF). The casting method produced thin films of (PVC) with various amounts of SiO2 nanoparticles (0.001, 0.002, 0.003, 0.004, and 0.005) g. XRD results showed that the PVC films and SiO2 NPs had an amorphous structure. The FESEM of PVC/SiO2 nanocomposite film shows excellent SiO2 dispersion on the PVC film surface. The FTIR spectrum indicated that SiO2 NPs did not influence polymer structure. UV-Vis spectroscopy has been used to study the effects of SiO2 NPs on PVC optical characteristics, including absorption spectrum, transmission spectrum, energy band gap, absorption coefficient, extinction coefficient, refractive index, and real and imaginary dielectric constants. It was found that with increasing SiO2 NPs amount, the optical energy gap of PVC/SiO2 nanocomposite films was reduced from 4.36 to 3.39 eV. The study shows that an increase in SiO2 NPs results in a change in all of these parameters.

Fabrication of nanocomposite films of polyvinyl alcohol/carboxymethyl cellulose (PVA/CMC) blended with Titanium dioxide nanoparticles (TiO2 NPs) by a modest solution casting technique is investigated. Also, TiO2 NPs and UV-irradiation effects for different intervals (12, 26, 40, and 48 hours) on the morphology (FESEM), structure (XRD), composition (FTIR) and optical properties (UV-Vis) of as-prepared films are inspected. FESEM images display that the morphology of PVA/CMC/TiO2 nanocomposite films is altered due to the strong influence of TiO2 NPs and UV exposure. The XRD spectra indicate that the amorphous phase of the samples has changed (decline or enhancement) due to UV exposure. The FTIR spectra demonstrate that the UV-irradiation period had a favourable impact on polymer structure by exhibiting some interesting IR peaks. Furthermore, the UV-Vis examination illustrates that the increased UV-irradiation times (12 h to 40 h) and TiO2 NPs addition improved the absorption intensity of the as-prepared films. Interestingly, the Energy gap Eg of the nanocomposite films was tuned from 4.47 eV to 5.01 eV with increased irradiation time (12 h to 40 h). In contrast, due to a higher increased UV-irradiation time of 48 h, the Energy gap Eg value of nanocomposite film was decreased to 4.62 eV. That can be attributed to the strong effect of UV exposure, which influenced the creation of structural defects. Finally, these findings prove that the PVA/CMC/TiO2 nanocomposite films have an amazing chance to be used in important optoelectronic applications.
