“…Figure 6a displays the refractive index n of the PVA/CuO nanocomposite lms before and after the irradiation process. The original lm's refractive index is 1.014, meanwhile, after being subjected to 3x10 17 ions cm − 2 and 6x10 17 ions cm − 2 , respectively, it increased to 1.020 and 1.030. As a result of the formed free radicals between the various chains of the irradiated samples, the refractive index rises with ion irradiation [41,42].…”

“…Because of this, it can be utilized to manufacture conductive sheets, electrodes, and sensors, among other electrical devices [15]. The superior electrical conductivity of CuO nano ller allows for quicker data transfer and better signal transmission, which in turn improves the overall performance and e ciency of an electronic device [16,17]. Its optical absorbance in the visible and near-infrared range makes it suitable for application in solar cells, photodetectors, and optoelectronic devices [18,19].…”

The solution casting production process was used to synthesis the composite PVA/CuO that is consisting of copper oxide nanoparticle (CuONP) with polyvinyl alcohol (PVA) for use in optoelectronic. The PVA/CuO composite were then irradiated with argon fluences of 3x1017, 6x1017, and 9x1017 ions.cm− 2 by cold cathode ion source. The XRD, FTIR, and UV/Vis are employed to investigate the structural, functional group, and optical impacts of PVA/CuO. In addition, the dispersion properties of the investigated films were calculated using the Wemple and Di-Domenico method, which led to the determination of various optical parameters. Pure and irradiated films were estimated for their optical susceptibility and refractive index. At the fluence of 6x1017 ions.cm− 2, the single oscillator energy Eo rises from 3.25 eV for the un-irradiated film to 3.89 eV and the dispersion energy Ed rises from 0.098 eV to 0.26 eV. Therefore, the results reveal that irradiated PVA/CuO composite are more applicable for optoelectronics.

In contrast to a polymer nanocomposite for high energy density application, a lead-free material such as zinc oxide (ZnO) and a non-toxic polymer matrix such as polyvinylidene fluoride (PVDF) can serve as a potential candidate for use in eco-friendly applications. In the present report, an effort has been made to enhance the dielectric behavior of the PVDF-based nanocomposites by adding ZnO nanoparticles (NPs) and TiO2-coated ZnO NPs (TZO) as nanofillers. A wet chemical precipitation technique was adopted to synthesize the thin films of PVDF and PVDF-ZnO, and PVDF-TZO nanocomposites. The structural, dielectric, ferroelectric, and energy density studies of PVDF, PVDF-ZnO, and PVDF-TZO nanocomposites thin films were performed for different concentrations (10%, 20%, 30%, and 40%) of nanofillers. Structural characterization carried out using X-ray diffraction studies confirmed the formation of PVDF-ZnO and PVDF-TZO nanocomposite thin films as the diffraction peaks (110) and (200) belonging to β-phase of PVDF, and (100, (002), (101), (110), (103), (200), (112), and (210) peaks were observed for ZnO, and (200), (116), (202) peaks belonging to TiO2 in case of PVDF+ 10% TZO and PVDF+40% TZO thin films. The functional groups belonging to β-phase of PVDF and ZnO were detected using a Fourier transform infrared spectrometer (FTIR). The surface microstructural of pure PVDF thin films showed spherulites and microimages of PVDF+ 10% ZnO and PVDF+ 10% TZO thin films depicted the inhomogeneous distribution of particles in the PVDF matrix. The maximum value of the dielectric constant, the maximum value of energy density, maximum remnant polarization, and the minimum value of dielectric loss for PVDF-TZO. PVDF-TZO thin films show an energy density of 65.3 µJ/cm3 for 40% of the nanofiller (TZO).

Free‐standing and flexible Polyvinylidene fluoride‐trifluoroethylene (P(VDF‐TrFE))—Copper (II) oxide (CuO) nanocomposite films were synthesized using the solution casting method. CuO nanoparticle weight percentage varied as 0%, 10% and 20% in the P(VDF‐TrFE) matrix. X‐ray diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy were employed for phase confirmation. The morphological changes with the content of CuO nanofiller in the P(VDF‐TrFE) matrix was examined using Field Emission Scanning Electron Microscope (FESEM). The thermal stability of the free‐standing films were tested by the Differential Scanning Calorimeter (DSC). The dielectric permittivity and loss tangent of the films were measured at 10.156 GHz using a Split Post Dielectric Resonator (SPDR) method. The results were verified with the Cavity perturbation technique at 9.174 GHz and showed a decrease in the dielectric properties with a rise in the weight percentage of CuO up to 20%. The present study demonstrates the comparison of the two techniques and the dielectric tunability in microwave frequencies.
