“…For each film, the ratio of solar radiation intensity with films present (symbol I) to solar radiation intensity without films present (symbol I o ) was computed and plotted, Almost all films have the same radiation intensity ratio as shown in the Figures (6-A, B, C, D, E, F) This was comparable with research [33].…”

The optical properties of polyvinyl chloride (PVC) and PVC/Zinc Oxide (ZnO) films were considered with different amounts of ZnONPs (0.001, 0.002, 0.003, 0.004 and 0.005) g. Using a Tetrahydrofuran (THF) solution all films be prepared by casting method. XRD results showed the amorphous structure of PVC film and Hexagonal crystalline structure of ZnO NPs, PVC/ZnO nanocomposites appear as pattern of PVC films so the peaks of ZnO don’t appear in it. FESEM image of PVC, ZnO and structure of PVC/ZnO nanocomposites seems to have cluster aggregates in different size. FTIR spectra revealed that ZnONPs had no effect on the polymer structure as there are no covalent bonds between PVC and ZnO NPs. Increasing the amounts of ZnONPs was seen to improve the optical properties (Absorbance, absorption coefficient and extinction coefficient) for PVC polymer. PVC polymer transmittance and energy gap decreased from 5.25 eV to 4.98 eV with increasing the amounts of ZnO NPs in nanocomposites. The solar radiation intensity in Baghdad was measured at a rate of 1 hour for the pure PVC films and PVC/ZnONPs for seven consecutive days in a rate from 6 A.M. to 6 P.M. (13 h). As can be observed, all films have the same ratio of transmitted radiation strength to sunlight intensity for all hours and days.

“…The solar radiation intensity in Baghdad for the pure PMMA films and PMMA/ZnO nanocomposites was measured at a rate of 1 hour for seven days in beginning in early September 2021, from 6 in the morning until 6 in the evening (13 h). As can be observed, almost all films have the same ratio of intensity of transmitted radiation to intensity of sunlight for all hours and days [34]. It is reasonable to deduce that the ratio of transmitted radiation strength to solar radiation intensity for all films is the same at all times and on all days.…”

Films of poly (methyl methacrylate) PMMA and PMMA doped with zinc oxide nanoparticles (ZnONPs) with different amounts were created using the solution casting technique. Different amounts of zinc oxide ranging from (0.001-0.005) g in step 0.001g were investigated and added to a polymer of constant amount (0.5) g of PMMA in 15ml Tetrahydrofuran (THF). It is known that increasing the amount of ZnONPs in this technique contributes to the appearance of ZnONP peaks within the polymer. The differences in the XRD spectrum show that the nanomaterial changed the microstructure of the polymer. This was discovered using a nanoscale scanning electron microscope (SEM). SEM revealed that the PMMA polymer surface exhibit an amorphous nature with a smooth surface. Fourier Transform Infrared (FTIR) spectroscopy demonstrates that there was no chemical reaction between the PMMA polymer and ZnONPs. Spectrophotometric measurements of absorbance and transmittance in the wavelength range 200- 900 nm were used to evaluate the optical characteristics of all films. Increased amounts of ZnONPs improve the absorbance, absorption coefficient, and extinction coefficient of PMMA polymer. With increasing ZNO content, the variance in computed optical energy gap values has been interpreted, the optical energy gap dropped from 4.65 eV to 4.10 eV. The solar radiation intensity in Baghdad for the pure PMMA films and PMMA/ZnO nanocomposites was measured at a rate of 1 hour for seven days in beginning in early September 2021, from 6 A.M to 6 P.M (13 h). As can be observed, almost all films have the same ratio of intensity of transmitted radiation to intensity of sunlight for all hours and days.

“…It refers to the capacity of a material to absorb light with a specific wavelength per unit length. Overall, if the value of the absorption coefficient was less than (α ˂ 104 cm-1) that means the indirect electronic transition occurred (32)(33)(34). 3).…”

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.
