“…In contrast to the XRD pattern of FeVO 4 , it was observed that the intensities of FeVO 4 peaks in the nanocomposites films dropped, and this indicated that FeVO 4 NPs were disseminated in the blend matrix. The emergence of nanofiller peaks in the blending pattern was documented in other studies 20,21 that with the addition of NiO or GeO 2 NPs to the PVC/PMMA mixture. The XRD data, in particular for 1.0 wt% FeVO 4 , support the important role of FeVO 4 NPs loading in raising the amorphicity of PU/PMMA mixture.…”

The best materials for enhanced energy storage capacitors in electrical systems are polymer nanocomposites films. Therefore, using the solution casting approach, we created a unique series of FeVO4 nanofiller‐embedded polyurethane (PU) and polymethyl methacrylate (PMMA)‐based composites. Various techniques were used to describe the prepared films. XRD spectra were used to assess the crystallinity and crystallite size of nanocomposites. The XRD spectra were used to assess the crystallinity and crystallite size of nanocomposites. With rising nanoparticles (NPs) content up to samples with 1.5 weight percent of FeVO4, XRD demonstrated an increase in the amorphous phase of the polymer mixture, which was further supported by UV–Vis measurements. FTIR was used for determining the complexation of the FeVO4 with the polymer mixture. Calculations were used to determine optical properties such as the Urbach energy and energy bandgap. With a rise in FeVO4 NP concentration, the energy bandgap decreases while the Urbach energy increases. All samples' AC conductivity spectra exhibit Jonscher's power law (JPL) behavior. Studies on dielectric permittivity and electric modulus have also been conducted in order to comprehend the charge storage characteristics and conductivity relaxation. Whereas the frequency‐dependent increase in AC electrical conductivity, the ε′ and ε″ of PU/PMMA–FeVO4 nanocomposites drop with the rising of the electric field frequency. The high level of FeVO4 was shown to improve the AC conductivity, ε′ and ε″ values of the nanocomposites. Tensile strength was improved by 38% with the addition of FeVO4 NPs into the PU/PMMA blend. Experimental outcomes show that these polymer nanocomposites materials are multifunctional and can be used as low‐permittivity nanodielectric insulators and substrates to design the next generation of flexible electronic devices and also there can be used to create a variety of advanced optoelectronic and organic electronic devices.

“…As a result of the space charges' inability to interact with the electric field at high frequency, dielectric loss decreases at high frequency as polarization‐related charge accumulation increases 52 . The NiFe2O4 NPs loading caused changes in ε ″ and ε ′ values, which were previously explained in the literature 53–56 by taking into account the homogeneity of the dispersed particles, the nature of the interactions between the nanoparticles and the polymer, change in the dipolar reordering, polar phases of the semicrystalline polymer, and so on.…”

Solid polymer electrolytes are an intriguing technology in terms of magneto‐opto electronic applications due to having a high dielectric constant, a small band gap, and excellent magnetic characteristics. In order to improve structural, optical, dielectric, conductivity, and magnetic characteristics, this research seeks to prepare nickel ferrite (NiFe2O4) nanoparticles and polyvinylalcohol (PVA)/carboxymethyl cellulose (CMC) films containing NiFe2O4. Nanoparticles of NiFe2O4 are prepared using the co‐precipitation method. The CMC/PVA–NiFe2O4 nanocomposites films are prepared using casting solution. To improve their structural, optical, conductivity, dielectric, and magnetic characteristics, these films electrolytes were examined using XRD, TEM, FT‐IR, UV–vis, and VSM measurements. According to the XRD analysis, the CMC/PVA blend polymer matrix demonstrates a considerable increase in amorphous nature with the NiFe2O4 nanoparticles (NPs) content, producing a highly flexible polymer backbone, increasing ionic conductivity of the CMC/PVA–NiFe2O4 nanocomposite films. The complexation of dopant cations with the CMC/PVA polymer matrix's backbone is confirmed by the FT‐IR spectroscopy. According to the UV–visible technique, the dopant NiFe2O4 concentration considerably affects the optical energy band gap, and Urbach energy of the pure CMC/PVA. At higher loading, these effects are more pronounced. At room temperature, ac conductivity, the dielectric behavior, and electrical modulus formalism were studied. The blend's highest AC conductivity is 4.77 × 103 S/cm. After increasing the loading of NiFe2O4 to 1.5 wt%, it increased to 8.07 × 104 S/cm. There has also been research on dielectric permittivity and electric modulus to further understand conductivity relaxation and charge storage qualities. The polymer nanocomposite, generally, displayed better optical, dielectric constant, conductivity, and magnetic characteristics compared to pure CMC/PVA being useable in terms of high energy storage nanoelectronics' manufacturing.Highlights NiFe2O4 nanoparticles were prepared by using the co‐precipitation method. Nanocomposite films of CMC/PVA–NiFe2O4 were successfully prepared by casting method. XRD patterns confirmed the increase in the degree amorphousity for nanocomposites films compare pure blend. From optical energy gap results for samples prepared was enhanced after addition NiFe2O4. The dielectric and magnetic properties showed that all nanocomposites films exhibited enhanced as compared to pure CMC/PVA film.

“…Figure 7 displays the relation between 2. The decrease in two energy gaps can be attributed to the emergence of defect states inside the nanocomposite, which facilitate electronic transitions [35,36]. Also, the decrease in indirect energy gaps is a result of variations at the level of polymer disorder, which occur due to alterations in the polymer structure caused by Mg 0.5 Ni 0.5 Fe 2 O 4 nanoparticles.…”

This study employed the sol gel auto-combustion approach to synthesize Mg0.5Ni0.5Fe2O4 spinel ferrite nanoparticles. Additionally, the casting method was used to fabricate Mg0.5Ni0.5Fe2O4/PMMA nanocomposite polymer films. The structural properties were analyzed by the utilization of x-ray diffraction pattern (XRD), high resolution transmission electron microscope (HRTEM), and field emission scanning electron microscope (FESEM). The UV-visible spectrophotometer examination was used to evaluate the optical properties of the produced nanocomposite films, such as absorbance, transmittance, indirect energy band gap, Urbach energy, excitation coefficient, and refractive index. Two indirect optical energy gaps are calculated, whereas they decreased from 4.56 eV to 4.33 eV, and from 4.04 eV to 3.01 eV, while the Urbach energy increased from 0.304 eV to 0.524 eV as the nanofillers increased from 0 to 4 wt%. An investigation was conducted to examine the impact of nanoparticle doping on the dielectric constant, electric modulus, and ac conductivity. The Mg0.5Ni0.5Fe2O4/PMMA nanocomposite films demonstrate higher permittivity and ac conductivity and a lower dissipation factor and electric modulus compared to pure PMMA. The dielectric permittivity (ε′) increased from 2.76 to 3.43 at a constant frequency 100 Hz up to 2 wt.% of Mg0.5Ni0.5Fe2O4 then decreased to 2.41 while the dissipation factor tan(δ) decreased from 0.1 to 0.046 at the same frequency. The nanocomposite films are well-suited for utilization in CUT-OFF selective laser filters, solar cells, energy storage devices, and other applications in related industries.
