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.

In order to produce suitable poly(methyl methacrylate)/poly(vinylidene uoride) (PMMA/PVDF) lms for optoelectronic and power storage uses, Ni-doped ZnO nanoparticles were added to PMMA/PVDF lms. This was done in order to generate a synergistic interaction between the superior electrical characteristics of Ni and the remarkable optical characteristics of ZnO NPs. The production of Ni/ZnO in wurtzite hexagonal phase with a normal grain size of 19 nm was veri ed by the ndings of the selected-area diffraction of electrons and X-ray diffraction techniques. By using FTIR measurements, the interaction of polymers with Ni/ZnO has been studied. The raising of the Ni/ZnO content steadily redshifted the optical band gap, although the Urbach energy demonstrated a contrary trend. With various nanoparticle concentrations, the differential scanning calorimetry (DSC) results revealed an enhancement in the temperature of melting of the PMMA/PVDF-Ni/ZnO nanocomposites lms as well as an decrease in the level of crystallinity. At room temperature, an AC impedance study was carried out to check the electrical conductivity. All samples' ac conductivity spectra con rmed Jonscher's power law (JPL) behavior. The PMMA/PVDF-1.5%Ni/ZnO nanocomposites were discovered to have a greater ionic conductivity (σac) of 1.10 10 − 5 S/cm at ambient temperature. Research on dielectric permittivity has additionally been carried out in order to comprehend the charge storage characteristics. The ndings of the experiments showed that these PMMA/PVDF-Ni/ZnO lms would provide excellent options for thermal insulators, cutting-edge microelectronics, capacitive storage of energy, optoelectronic technology and other applications.
