Nanocomposites have a wide range of applications, including optical integrated circuits, sensors, coatings, and medical devices. As a result, the purpose of this paper is to prepare a new type of nanocomposites made of polyvinyl alcohol (PVA) with different concentrations (0, 1, 2 and 3) wt% of cobalt oxide and zirconium dioxide (CoO-ZrO2) nanoparticles by using casting method. Microscopic photographs demonstrate the fact that the additive distribution amount of NPs in the polymer was uniform, and (CoO-ZrO2) NPs formed a continuous network within the polymer when the concentration reached 3wt.%. The outcomes of optical properties indicate that the absorbance of nanocomposites improves as the concentrations of cobalt oxide and zirconium dioxide nanoparticles increase while transmittance and the optical energy gap decrease. On the other hand, optical constants of nanocomposites (refractive index, absorption coefficient, extinction coefficient, real and imaginary the dielectric constants) and optical conductivity are increase with increases in the weight percentages of (CoO-ZrO2) nanoparticles. These outcomes demonstrate the (PVA-CoO -ZrO2) NCs use for various optical devices.

“…Tantalum Carbide (TaC), which is also a very promising ultra-high temperature material, has been found to be wear-resistant as well as to have biocompatible qualities that make it suitable for biomedical applications [12,13]. TaC has drawn investigation, but thorough comprehension has eluded researchers because, like other transition-metal carbides, it appears in a broad variety of compositions, and as a result, its physical characteristics vary.…”

In this study, the casting method was used to prepared PMMA/Si3N4/TaC nanocomposites with variant content (0,2,4,6,8) % wt of Si3N4/TaC nanoparticles. The structural and electrical properties have been investigated. Scanning electron microscope (SEM) indicate that the homogenous, smooth and dispersed of Si3N4 and TaC NPs inside the PMMA matrix due to strong covalent interaction between the Si3N4 and TaC NPs in the PMMA matrix which mean a good method for prepared films. Optical microscope images explained that when increasing in content of nanoparticles that forming network paths inside the polymeric matrix that act as charge carriers. FTIR spectra indicate to a physical interference between the polymer matrix and nanoparticles. The AC electrical properties of nanocomposites obtained that the dielectric constant and dielectric loss rise with rising content of nanoparticles and decrease with rising frequency of applied electric field. While the A.C electrical conductivity rise with rising the frequency and weight content of Si3N4/TaC nanoparticles. This results indicated that the PMMA/Si3N4/TaC nanostructures can be considered as promising materials for electronics and electrical nanodevices.

The blends obtained were subjected to characterization using SEM (scanning electron microscopy) and XRD (x-ray diffraction). By utilizing diffuse reflectance measurements, an extensive investigation into different optical properties was carried out, covering energy band gap, refractive index, extinction coefficient, dielectric constant, conductivity, as well as nonlinear optical properties. After the incorporation of CNPs /CuCo2O4 in the polymer, the transmittance of the PMMA experienced a decline from 92% to 42%, while the absorbance, reflectance and refractive index exhibited an increase. As the blend incorporated CuCo2O4, a continuous reduction in both direct and indirect optical band gap energies of PMMA (4.94 and 4.69 eV) was observed attaining 4.4 and 4.37 eV for 2.5 wt.% CuCo2O4, respectively. It is noteworthy that the initially inadequate optical conductivity of PMMA exhibited a significant improvement, leading to enhanced linear and nonlinear optical parameters with increasing CuCo2O4 doping levels. Analysis of fluorescence spectra (FL) revealed a decrease in FL intensity and a shift in maximum position as the CuCo2O4 content (x) increased, resulting in the generation of the CIE chromaticity diagram. Dielectric measurements provided insights into the impact of CuCo2O4 content on alternating current (AC) conductivity, energy density, dielectric properties, and electric modulus across all blends.
