“…MgO nano-belts were made using a DC arc plasma jet chemical vapor deposition approach [14], while MgO nanofibers were made using a hydrothermal method [15]. Biodegradable, biocompatible, non-toxic, and easy-to-process synthetic polymers, such as poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP), have a wide range of biomedical, engineering, and technical uses [16,17]. When using the solution casting process, these polymers are water-soluble and produce very optically clear films.…”

“…The successful incorporation of boehmite within the macromolecular chains of polymer blend is evident from the appearance of characteristic peaks of boehmite in the XRD pattern of the nanocomposite. All these observations demonstrate the possible interactions occurring between the polymer blend network and boehmite nanoparticles, which will eventually lead to the enhancement of properties 27 …”

“…Additional blend‐specific bands with a minor shift in their relative positions can be seen in the spectra of nanocomposites. Moreover, the new peaks corresponding to the AlO vibration of boehmite that appear at around 712–728, 610–646 and 427–437 cm −1 in the IR spectrum of nanocomposites also give strong evidence for the successfully incorporated nanoboehmite 27 …”

This work reports on a bio‐based polymer blend comprised of polyvinyl alcohol/cashew gum (PVA/CG) embedded with boehmite nanoparticles to tailor the structural, thermal, mechanical properties, and electrical response. The chemical bonding between boehmite and the PVA/CG blend was confirmed by FTIR. The XRD data showed that the nanocomposite films had distinct peaks of boehmite. The SEM images revealed uniformly dispersed morphology at 5 wt% boehmite. The elemental composition of blend nanocomposites was revealed by the EDX analysis. The thermal stability of the blend increases with increasing boehmite, whereas the glass transition temperature decreases. The highest AC conductivity was achieved for PVA/CG/7 wt% boehmite, which was 4.6 times greater than the pure blend. The frequency and temperature‐dependent dielectric constant, modulus and impedance of all films were examined in conjunction with different nanoparticle loadings. Tensile strength and hardness have improved with the addition of boehmite into the PVA/CG blend whereas the elongation at break slightly decreases. The PVA/CG blend had a tensile strength of 31.17 MPa, which increased to 44.66 MPa when 7 wt% boehmite was added. Therefore, eco‐friendly PVA/CG/boehmite films with good thermal stability, mechanical strength, dielectric constant, and conductivity could be a practical green substitute for flexible electronic, charge storage, and electrochemical devices.

“…High surface area leads to a change in the macromolecular state around the nanoparticles (e.g., concentration gradient, crystallization, and altered mobility), which transforms the overall behavior of the material. [ 3 ] Poly (vinyl alcohol) (PVA) is a semicrystalline polymer having high dielectric strength, respectable thermal stability, high mechanical strength, chemical resistance, excellent film‐forming properties, and optical transparency. [ 4 ] The presence of the hydroxyl group, (–OH), gives PVA superior properties because of the strong hydroxyl group interaction between intramolecular and intermolecular polymer chains.…”

Nanocomposites based on poly (vinyl alcohol) (PVA) filled with different types of nanometal oxides named MgO, Al 2 O 3 , and CuO were attained from an aqueous solution of PVA. PVA/nanometal oxide films were achieved by the solution casting procedure. The prepared nanocomposites were subjected to a gamma radiation dose at 50 kGy to study the impact of ionizing radiation on the various properties of the prepared samples. In this context, this work was mainly concerned with the differences in the behavior of various metal oxides, as well as the effect of ionizing radiation on the tensile strength (TS), elongation at break (E%), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction, and optical characteristics of the fabricated specimens. Furthermore, Fourier transform infrared (FTIR), SEM, and thermodynamic factors (E a , ΔH, ΔG, and ΔS) were considered. FTIR and the suggested reaction mechanism supported that the hydroxyl groups of PVA have a really strong affinity to form charge-transfer complexes with different nanometal oxides done chelation. In general, the interference of 0.1% of all studied nanometal oxides improved TS, thermal stability, melting temperature, and optical properties of PVA, whereas PVA/0.1 CuO was the best. Moreover, gamma radiation exposure enhanced the different properties of native PVA and displayed anisotropic behavior toward its nanocomposites.
