“…Recently, ZnO/PVA-based composite membranes have gained a lot of attention. Asadpour et al, 2022, explain the unique structural and functional characteristics of how ZnO/PVA membranes offer significant promise in a variety of electrical, optical, and water treatment applications [ 37 ]. Abdullah et al, 2021, found that ZnO-PVA membranes’ ionic conductivity has been examined over a wide frequency range and at various temperatures [ 38 ].…”

The current study investigated the development and application of lithium (Li)-doped zinc oxide (ZnO)-impregnated polyvinyl alcohol (PVA) proton exchange membrane separator in a single chambered microbial fuel cell (MFC). Physiochemical analysis was performed via FT-IR, XRD, TEM, and AC impedance analysis to characterize thus synthesized Li-doped ZnO. PVA-ZnO-Li with 2.0% Li incorporation showed higher power generation in MFC. Using coulombic efficiency and current density, the impact of oxygen crossing on the membrane cathode assembly (MCA) area was evaluated. Different amounts of Li were incorporated into the membrane to optimize its electrochemical behavior and to increase proton conductivity while reducing biofouling. When acetate wastewater was treated in MFC using a PVA-ZnO-Li-based MCA, the maximum power density of 6.3 W/m3 was achieved. These observations strongly support our hypothesis that PVA-ZnO-Li can be an efficient and affordable separator for MFC.

ZnO/PVA nanocomposites have been successfully synthesized using the spin coating method by using synthesized ZnO, ZnO nanoparticles as filler, and PVA as a matrix. The synthesized films were treated at temperatures of 70, 90, and 120 °C. Some characterizations, such as I-V, UV-Vis, XRD, and SEM, have been carried out to study the electrical, crystalline, and optical properties of ZnO/PVA nanocomposites. The characterization of electrical properties using I-V measurements showed that ZnOsynthesized/PVA had a high current value of 1.55 nA, while ZnOnano/PVA had a smaller current value of 1.49 nA when treated at 120 °C. In addition, the higher the treatment temperature, the greater the resistance of ZnOsynthesized/PVA and ZnOnano/PVA. UV-Vis characterization showed that ZnOnano/PVA experienced a red shift when the temperature increased, while ZnOsynthesized/PVA and ZnOnano/PVA when treated at 120 °C experienced a blue shift. XRD characterization of ZnOnano/PVA showed that the higher the given temperature, the lower the crystallinity, from 45.77 to 34.81%. SEM characterization showed that ZnOnano/PVA at room temperature agglomerated and formed larger particles.

“…[25][26][27] It has been demonstrated that ZnO has positive effects on the properties of PVA. [28][29][30] The mechanical and antibacterial properties of PVA are improved in the presence of 3 wt% and 5 wt% of ZnO nanoparticles, owing to the intermolecular forces between the fillers and the PVA macromolecular chains. 31 Another approach for enhancing the PVA properties is the loading of a three-dimensional (3D) network structure into the PVA matrix, achieved through the preparation of double network PVA hydrogels.…”

New polyvinyl alcohol (PVA) nanocomposites containing zinc oxide (ZnO) nanoparticles and a hydrogel were prepared by the solution casting method. ZnO nanoparticles grafted co‐polymer (Zn‐g‐CP) was synthesized through the reaction of ZnO nanoparticles with vinyltriethoxysilane and then the radical co‐polymerization with 2‐acrylamido‐2‐methylpropane sulfonic acid (AMPS). The amide functionalized hydrogel was prepared via an in situ polymerization of acrylamide and N,N′‐methylene bisacrylamide (MBA) as a crosslinker in a solution of PVA. The corresponding results indicated that the simultaneous presence of both Zn‐g‐CP and hydrogel could significantly increase flammability, thermal stability, and the tensile strength of PVA. The results of the X‐ray diffraction (XRD) and field‐emission scanning electron microscopy (FE‐SEM) indicated a uniform dispersion of ZnO nanoparticles and an enhanced compatibility with the PVA matrix. Thermogravimetric analysis (TGA) in both N2 and air atmospheres, indicated that the temperature at 50% mass loss and the char residue values of PVA nanocomposite containing 6 wt% of Zn‐g‐CP in the presence of hydrogel (PZH12 sample) were enhanced, which was evident by the increased thermal decomposition temperature. The peak of heat release rate (pHRR) value of the PZH12 sample was obtained 56.9% lower than that of the neat PVA demonstrating a significant improvement in flammability behavior. Also, the flame‐retardant performance of PZH12 improved, as compared to the pure PVA, with UL‐94 V1 rating and LOI of 27.2%. The tensile strength (Ts) and elongation at break (EB) values for the mentioned sample enhanced by 62.5% and 7.2% compared to those of the neat PVA, respectively.Highlights Preparation of vinyl functionalized ZnO nanoparticles (VZnO).

The effect investigation of hydrogel and Zn‐g‐CP on the PVA properties. The results exhibited the enhanced flame retardancy and mechanical properties of PVA.
