“…It can be seen that  2 is dependent on k values, which is changed with changing the absorption coefficient due to the relation between  and k. This behaviour is consistent with the results of Refs. [41,42].…”

еВ та з 2,79 еВ до 2,18 еВ для дозволеного та забороненого непрямих переходів відповідно, коли додавання наночастинок оксиду Феруму досягає 6 мас.%. Ця особливість може відігравати життєво важливу роль у створенні нанокомпозитів ПОЕ/ПВС/Fe 2 O 3 для майбутніх застосувань в оптоелектроніці. Показник заломлення, коефіцієнт екстинкції, діелектрична проникність і оптична провідність збільшуються зі збільшенням концентрації наночастинок оксиду Феруму. Досліджено антибактеріальні властивості нанокомпозитів ПОЕ/ПВС/Fe 2 O 3 щодо бактерій E. coli. Експериментальні результати показують, що діяметер зони інгібування збільшується зі збільшенням концентрації наночастинок оксиду Феруму. Нарешті, нанокомпозити ПОЕ/ПВС/Fe 2 O 3 мають гарну антибактеріяльну активність.

“…Due to free charge motion inside the material, the dielectric loss for (PEO/PVA/SrTiO3/NiO) NCs becomes quite significant at lower frequencies. Furthermore, these NCs have a significant dielectric loss because electric dipoles have ample time to align with the applied electric field before their orientation changes [30,31,32]. At 100 Hz, figure.…”

Films are prepared from (PEO/PVA) blend with various ratios of (SrTiO3/NiO) by using casting method. SEM images of (PEO/PVA/SrTiO3/NiO) nanocomposites show that many aggregates or chunks on the upper surface that are homogeneous and coherent. The (PEO/PVA/SrTiO3/NiO) nanocomposites contribute to tiny vibrational molecular movement, according to the (FTIR) analysis. Several polymer chains were also disrupted once (SrTiO3/NiO) nanoparticles were introduced. Instead, several additional chains were produced. Dielectric constant and dielectric loss decreases with increasing of frequency, while conductivity increases, as well as dielectric constant increases from 4.73 to 5.99 and dielectric loss rise from 0.85 to1.80, while the conductivity increases from 4.7×10-11 S/cm to 1.10×10-10 S/cm when (SrTiO3/NiO) NPs reached 4wt.%. The results of structural and electrical properties show that the (PEO/PVA/SrTiO3/NiO) NCs may be used for various electronics fields.

We study the impact of (MnO2–ZrO2) nanoparticles on optical properties of (PVA) polymer. Several samples were produced with different weight ratios of (MnO2–ZrO2) nanoparticles. To prepare the selected samples, the casting method is used. To record the absorption spectrum, wavelengths of 200–1100 nm are applied. We have determined the absorption coefficient, energy gap for indirect transitions (forbidden and allowed), optical constants (such as the dielectric constant with its imaginary and real parts, refractive index, and attenuation coefficient), and optical conductivity. The results indicate that there is a proportional relationship between the optical constants and the concentration of (MnO2–ZrO2) nanoparticles, which means that an increase of the concentration of (MnO2–ZrO2) nanoparticles leads to an increase of the optical constants, while the transmission decreases. Additionally, the optical energy gap decreases from 4.83 eV to 3.4 eV and from 4.65 eV to 3.28 eV with increasing the concentration of (MnO2–ZrO2) nanoparticles for allowed and forbidden indirect transitions, respectively. These results can be considered as key ones for the use of (PVA-MnO2–ZrO2) nanocomposites in various fields such as optoelectronics and photonics.
