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.

“…Hence, due to insufficient time, the dipoles are unable to follow the field variation at higher frequencies [32]. The dielectric constant and dielectric loss decrease with the increase of Sb 2 O 3 nanoparticles concentration, this result can be attributed to the increase in conductivity as a result of the increase charge carrier density in polymer matrix [33,34]. Figure14 shows the variation of the A.C electrical conductivity of (PEO-PVA-Sb 2 O 3 ) nanocomposites with frequency.…”

In this work, the (PEO-PVA-Sb 2 O 3 ) nanocomposites were prepared from (PEO-PVA) blend with different concentrations of the Sb 2 O 3 nanoparticles by using the casting method to used it for different modern applications such as: antibacterial, humidity sensors, solar cells, diodes, thermal energy storage and release …etc. The structural, optical and dielectric properties of (PEO-PVA-Sb 2 O 3 ) nanocomposites have been studied. The results of optical properties for nanocomposites showed that the absorbance has high values at UV region. Also, its increase while the transmittance and energy band gap reduce of (PEO-PVA) blend with the increase in Sb 2 O 3 nanoparticles concentrations. The absorption coefficient, extinction coefficient, refraction index, dielectric constant and optical conductivity are increased with the increase in Sb 2 O 3 nanoparticles concentrations. The dielectric properties of nanocomposites showed that the dielectric constant, dielectric loss and A.C electrical conductivity of (PEO-PVA) blend increase with the increase in Sb 2 O 3 nanoparticles concentrations. Also, the dielectric constant and dielectric loss of (PEO-PVA-Sb 2 O 3 ) nanocomposites decrease while the A.C electrical conductivity increases with the increase in frequency. finally, the (PEO-PVA-Sb 2 O 3 ) nanocomposites tested for antibacterial applications. The results showed that the the (PEO-PVA-Sb 2 O 3 ) nanocomposites have good activity for antibacterial.

In this work, preparation of PVA/ZrC nanostructures and studying the optical properties to employ in different optical fields. The PVA/ZrC nanostructures were fabricated using casting method. The optical properties were measured at wavelength ranged from 200 nm to 800 nm. Results showed that the absorbance(A) of polymer was rise while the transmittance (T) was reduced with rise in the ZrC NPs ratio. The energy gap(Eg) was reduced as the ZrC NPs ratio rises. Also, the results of optical properties indicated that the PVA/ZrC nanocomposites have high absorption at UV region.
