“…Additionally, additional doping of Ni/ZnO NPs raised the blend's amorphous level; as a result, the free volume around the blended network rose, increasing the mobility of polarons and bipolrons [44]. Additionally, chain scissoring and further degradation of the polymer chains cause the electrical conductivity to rise the most following the addition of Ni/ZnO NPs, which speeds up ionic transport through the polymer model [45].…”

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. HighlightsNanocomposite samples of PMMA/PVDF-Ni/ZnO nanocomposites were successfully prepared by using the casting technique.XRD patterns con rmed the increase in the degree amorphousity for nanocomposites lms compare PMMA/PVDF blend.From optical energy gap results for samples prepared was reduced after addition Ni/ZnONPs. DSC results revealed an enhancement in the thermal stability of the PMMA/PVDF-Ni/ZnO lms The conductivity and dielectric properties showed that all nanocomposites lms exhibited improved as compared to pure PMMA/PVDF lm.
