Summary: This review article focuses on the application and development of solid polymer electrolytes (SPEs) based on polyvinyl alcohol (PVA) in supercapacitors. The discussion includes the influence of PVA as a host polymer and conducting salts, the formation of SPEs, and the ion transport mechanism. The review also highlights the fundamentals of electrochemical characterization and thermodynamic transport models of ions, and discusses methods for enhancing the electrochemical performance of PVA-based SPEs and the challenges they currently face.

Summary: In this study, PVA nanocomposite films were prepared with montmorillonite and titanium oxide nanoparticles, and the effect of nanofiller concentrations on barrier properties was optimized using response surface methodology. The viscosity of the polymer-forming solution increased with the addition of nanoparticles, leading to better distribution at low concentrations but aggregation at high concentrations. The best barrier properties were achieved with a combined loading of 1 wt% TiO2 and 4 wt% MMT.

Summary: Nanocomposite PVA/PEG/PVP/SnS2/V films were prepared via thermolysis and casting procedures, and their thermal stability was improved. The effects of doping on optical parameters and emitted colors were investigated. It was found that the nonlinear optical parameters were effectively improved with increasing percentage of SnS2/V dopant.

Summary: This study aimed to prepare a reinforced composite packaging film composed of soy protein/polyvinyl alcohol (PVA) and nano-TiO2. Various film compositions were designed by adjusting the particle size, concentration, and dispersing agent (PVP) of nano-TiO2, as well as the pH of the film casting solution. The optimized film composition was determined to be 2.5 wt% nano-TiO2, 30 nm particle size, 1.5 wt% PVP, and pH 6.0. The addition of nano-TiO2 improved the thermal stability of the soy protein/PVA film, as confirmed by scanning electron microscope (SEM) and differential scanning calorimetry (DSC) analysis.

Summary: The study demonstrates that incorporating super-acidic sulfated zirconia into a binary polymer blend can enhance the physicochemical properties of composite membranes, leading to increased power density and decreased permeability and swelling ratio. Membranes with 7.5% SO4ZrO2 exhibit power density close to that of commercial Nafion117, highlighting the promising future applications of cost-effective and eco-friendly DBFC membranes.

Summary: Dielectric measurements were performed on the sulfonated polyvinyl alcohol (SPVA) membrane in liquid electrolytes. A clear Maxwell-Wagner relaxation effect was observed, which varied with the membrane's sulfonation degree and Li+ concentration. The permittivity and conductivity were evaluated using a model-free approach. The results indicated that both the membrane conductivity and bulk solution conductivity initially increased and then decreased with increasing Li+ concentration, reaching their maximum values at different concentrations, suggesting different mechanisms of Li+ migration. Ion distribution coefficient, membrane volume charge density, and Li+ solvation energy barrier were calculated, and a possible mechanism was proposed: Li+ migration is primarily driven by the interaction between fixed charges in the membrane and polarized charges at the interface, governed by Donnan equilibrium or dielectric repulsion at lower or higher lithium salt concentrations.

Summary: Recycled aggregate concrete (RAC) has become a prominent research area due to its utilization of construction waste. The addition of nano-SiO2 (NS) and fiber such as polyvinyl alcohol (PVA) can significantly improve the mechanical properties of RAC. SEM analysis shows that NS fills micro-pores and cracks in RAC, while PVA fiber enhances the contact between recycled aggregate and mortar, resulting in a more compact microstructure.

Summary: Three-phase polymer electrolyte nanocomposites composed of PVA, MnCl2, and MWCNTs were prepared and their AC electrical conductivity was investigated using impedance spectroscopy. The temperature and frequency-dependent conductivity behavior was explained using the Jonscher's power law. The CBH and QMT models were used to explain the conduction mechanism of the samples at different temperatures.
