“…The particle size seems to be in the micro-size range, which is bigger than the size measured by XRD given in figure 1. This is a usual note, as SEM gives the size of the grains and each grain is consists of several crystals [26]. The surface morphology of PVA/PEO and the blend loaded with 3-12 wt.% clay Nps was investigated by taking images using FE-SEM, as shown in figure 2.…”

“…Increasing clay Nps content to 9% increase the IP and thus ε′, but at 12% clay Nps the phase segregation of the nanofillers reduce the IP. Moreover, below 9% clay Nps content, the functional groups of the blend may get an ordered state that causes an increase in ion mobility in the polymer blend matrix [26].…”

Synthesis of polymeric blends and nanocomposites of tuned properties gained increasing attention worldwide. In the present report, semicrystalline PVA/PEO blend films loaded with clay nanoparticles (Nps), at doping ratios in the range 3-12 wt%, were prepared and characterized by various techniques. XRD, SEM, and FTIR were used for probing the semicrystalline nature, morphology, and microstructure of the blend and complexation between its constituents. UV-vis-IR spectroscopy was performed to study the optical properties and optical constants of the prepared nanocomposites. Moreover, the dielectric properties were studied in the frequency range 0.1 Hz to 20 MHz and at different temperatures. Clay Nps incorporation decreased the blend crystallinity and affect its surface morphology without changing the blend structure. Strong interaction and complexation between the films' constituents are noted through the change in XRD peaks position and FTIR band intensity. The values of optical transmittance and absorption index of the films as well as the bandgap (E g ), refractive index (n), and optical dispersion parameters depend mainly on the clay Nps doped ratio. The direct E g decreased from 4.5 to 3.9 eV and n increased from 3.28 to 4.78. The dielectric constant, dielectric loss tangent, dielectric moduli (M′, M″), and ac conductivity were improved with the clay Nps content and also influenced by the temperature. The nature of the relaxation peaks in tan (δ) and M″ indicate the deviation of the conduction process from the ideal Debye type behavior. Increasing the semiconducting nature and the value of ac conductivity encourage the utilization of these nanocomposites in various electric and optoelectric applications.

“…On the other hand, CuO is a semiconductor that has bandgap in the range of 1.2–1.5 eV, good thermal and electronic features and generally used in superconductors, supercapacitors, and solar energy purposes 20 . In addition, Cu 2 O is a non-toxic material and has a narrow direct optical band gap in the range of 1.9–2.3 eV and therefore employed on optoelectronic devices 21 .…”

ZrS2 is transition metal dichalcogenides (TMDCs) which is believed one of the most talented applicants to fabricate photovoltaics. Therefore, we present here for the first-time numerical simulation of novel inorganic ZrS2/CuO heterojunction solar cells employing SCAPS-1D. The influence of the thickness, carrier concentration, and bandgap for both the window and absorber layers on the solar cell fundamental parameters was explored intensely. Our results reveal that the solar cell devices performance is mainly affected by many parameters such as the depletion width (Wd), built-in voltage (Vbi), collection length of charge carrier, the minority carrier lifetime, photogenerated current, and recombination rate. The η of 23.8% was achieved as the highest value for our simulated devices with the Voc value of 0.96 V, the Jsc value of 34.2 mA/cm2, and the FF value of 72.2%. Such efficiency was obtained when the CuO band gap, thickness, and carrier concentration were 1.35 eV, 5.5 µm, and above 1018 cm−3, respectively, and for the ZrS2 were 1.4 eV, 1 µm, and less than 1020 cm−3, respectively. Our simulated results indicate that the inorganic ZrS2/CuO heterojunction solar cells are promising to fabricate low-cost, large-scale, and high-efficiency photovoltaic devices.

“…Finally, C H bending is ascribed to the bands at 755 and 487 cm À1 . 27 The IR spectra of CuO nanoparticles show its characteristic absorption bands at 607 and 515 cm À1 . In the FTIR of nanocomposites, these two peaks merged into a single signal at 599 cm À1 , indicating the strong interaction between the CuO and PMMA.…”

Polymethyl methacrylate (PMMA) with varied compositions of copper oxide (CuO) nanoparticles was synthesized using in‐situ free radical polymerization. UV–visible, FT‐IR, XRD, FE‐SEM, DSC, and TGA were employed to examine their structure, morphology, and thermal properties. The broadening and intensification of UV absorption, as well as the shift in IR peaks of PMMA with the addition of CuO, confirm their interactions. The reduction in optical bandgap values with the reinforcement of nanofillers confirms the existence of intermediate energy bands in nanocomposites. XRD indicated that polymerization with CuO reduced the amorphous nature of PMMA. The FE‐SEM image revealed that the dispersion of CuO altered the nonporous, rough surface of PMMA into a homogeneous shape. The reinforcement of CuO enhanced the thermal stability and glass transition temperature of PMMA. The mechanical strength, modulus, impact strength, and rigidity of PMMA were significantly improved through in‐situ polymerization. The electrical property analysis revealed that the AC conductivity increased with frequency, temperature, and filler content. The reduction in activation energy of AC conductivity with temperature points toward their semiconducting nature. PMMA/CuO nanocomposites with higher tensile strength, lower bandgap energy, higher conductivity, and thermal properties can be used to make flexible optoelectronic devices.Highlights A series of PMMA/CuO nanocomposites were synthesized and characterized. Enhanced optical property, thermal stability, and glass transition temperature. Possess excellent dielectric constant and AC conductivity. Mechanical strength and impact resistance of PMMA were greatly enhanced. A promising material for flexible optoelectronic and power storage applications.
