Numerous applications for optical technologies used the nanocomposites. The purpose of this work is to create novel kinds of polymer nanocomposites and analyze their optical characteristics. The polyvinyl pyrrolidone (PVP)/ manganese oxide nanoparticle (MnO2NPs) nanocomposites were created. Various content of PVA and MnO2 NPs were fabricated. The optical characteristics of these nanocomposites were examined. The results demonstrate that the absorbance, coefficient of absorption, index of refractive, coefficient of extinction, dielectric constant and conductivity of PVP are raise with arise of the MnO2NPs content. The transmittance and gap of energy are reduced with a rise of the MnO2NPs content. The results illustrated the PVP/MnO2nanostructures may be utilized in different photonics and optics fields.

“…The dielectric constant was calculated for the pure (PVA) polymer film and the (PVA:PoPDA-GO-MgO) nanocomposite films varying the weight ratios (2,4,6,8, 10wt%) at room temperature (25 o C) as shown in figure (4), when it can be seen from the graph that the dielectric constant drops as the frequency increases and for the films of all hybrid nanocomposites [30]. Dipolar groups in insulating polymers can arrange themselves in the direction of the electric field at low frequencies, but it is difficult for this group (Dipoles) when it is large to arrange itself towards the fast and time-varying electric field at high frequencies because the time period is short less than the time it takes for the molecules to be able to arrange themselves in the direction of the outgoing electric field, the electronic polarization occurs within a very short but longer period of time than the ionic polarization, while the dipole polarization takes a relatively long time compared to all polarizations, therefore the dielectric constant of non-polar polymers remains almost constant at high frequency and therefore (ε̍ ) values decrease dramatically and sharply with increasing frequency in low frequency regions [31], this may be the reason for the decrease in (ε̍ ) values with increasing frequency.…”

In this work, a pure (PVA) polymer film reinforced with magnesium oxide, graphene oxide poly (o-phenylene diamine) (GO-MgO-PoPDA) was created utilizing the solution casting process in various weight ratios (0, 2, 4, 6, 8, 10 wt%). It was investigated how varied weight ratios of the nanoparticles magnesium oxide (MgO) and graphene oxide (GO) affected the Dielectric Properties of nano composite films. FTIR, SEM,X-RAY were used to characterized the nanocomposite. The results of the dielectric properties showed that the values of the alternating electrical conductivity of the prepared films increase when adding (GO-MgO-PoPDA) nanoparticles and with the increase of the frequency of the applied electric field and the increase of the particle content, while the values of the dielectric constant increase with the increase of each of the content of (GO-MgO- PoPDA) nanoparticles, but it decreases with increasing frequency. Whereas, the dielectric loss coefficient of the prepared films decreases when nanoparticles are added and with increasing frequency.

This work is devoted to optimizing the optical and dielectric parameters of polyvinyl alcohol (PVA): polyvinyl pyrrolidone (PVP) (1:1) polymer nanocomposites by controlling barium stannate contents (BaSnO3) aspiring to engage it into flexible optoelectronics and thermally stable capacitors. Herein, high purity BaSnO3 was synthesized by solid‐state route and loaded with different ratios (5–20 wt%) into PVA/PVP blend to form films by solution casting method. Further, the degree of crystallinity (Xc) was highly increased upon increasing the filler contents (BaSnO3), as confirmed by X‐ray diffractometer measurement. The surface morphology pictured by a field emission scanning electron microscope revealed the variation of the surface from smooth to rough surface upon insertion of BaSnO3. The thermodynamic parameters including enthalpy (ΔH), entropy (ΔS), and Gibb's free energy (ΔG) were extracted from TGA measurements and studied in detail. The optical characteristics of plain PVA/PVP and polymer nanocomposite films are explored by UV–Vis–NIR spectrophotometer. The presence of charge‐transfer complexes within the polymer nanocomposites was certified via shifting of band gap energy from 5.02 to 4.33 eV and variation of band tailing energy (Eu) from 0.22 to 0.44 eV. The real and imaginary part of optical conductivity (σp1, σp2) was confirmed to be enhanced with the insertion of BaSnO3. It is also found that the dielectric constant and DC current increased with the insertion of BaSnO3 content, while the dielectric loss decreases. The findings recommend these polymer nanocomposites as a good candidate for green energy applications and high‐performance capacitors.
