“…The influence of In2O3 NPs content on the ε' and ε" of PVA/PEG/In2O3 nanostructures are illustrated in Figures 3 and 4. The rise in values of ε' and ε" related to increase the charge carriers [18][19][20][21][22][23][24][25]. On the other hand, at high frequencies, dielectric constant and dielectric loss were found to be relatively constant with frequency.…”

The dielectric characteristics of PVA/PEG/In2O3 nanostructures were tested to use in various electric nanodevices. The films of nanostructures of PVA/PEG/In2O3 were synthesized by casting solution technique. The dielectric characters of PVA/PEG/In2O3 nanostructures were determined. Results expressed that the dielectric parameters of PVA/PEG were rise with rise in the In2O3 NPs ratio. The performance of ε', ε" and σAC with frequency illustrated that the ε' and ε" reduced whereas the σAC rises with rise in frequency. The final results demonstrated the PVA/PEG/In2O3 nanostructures may be suitable in various electrical nanodevices.

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.

“…The values of the energy gap decrease as the percentage of Fe 2 O 3 nanoparticles increases. The creation of localized levels inside the forbidden energy gap is responsible for this occurrence [31][32][33].

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.
