This review provides a comprehensive overview on applications, preparation methods, and most notably the performance efficiency of polyvinyl alcohol (PVA)-based membranes for filtration of aqueous environments. Incorporation of PVA into the membrane matrix significantly enhances such characteristics as antifouling and antibacterial properties as well as hydrophilicity and permeability in the water and wastewater filtrations. Contribution of different PVAbased modular membranes for water purification targets via a comparative review on previous researches is the main theme in this work. Alongside with the focused topic, some basic theories and principals of blend and composite polymer films as well as polymer fibers are debated before the main discussions. This review will ultimately facilitate further development of PVA membranes for the future investigations.

“…[39] These peculiar properties make VOx highly promising for glucose electrooxidation; nevertheless, systematic research is still lacking and filled with open questions. To the best of our knowledge, the first and only study on this was by Azharudeen et al [40] of a hybrid PVA/VO 2 electrode obtained through wet chemistry methods. However, the authors reported only one anodic wave in the forward scan and no anodic peaks in the backward scan.…”

In the search for non‐enzymatic alternatives to glucose oxidase, reliable and microchip‐compatible approaches to catalyst development are highly desirable. Herein, the electrochemical behavior of thin films of VOx deposited by molecular beam epitaxy (MBE) on glassy carbon electrodes is reported . A process of partial etching during polarization is observed. Thereafter, highly active and stable traces of VOx act as catalytic centers for glucose electrooxidation. A mechanistic description of the electrochemical process is proposed based on evidence provided by voltammetric measurements. The sensors are calibrated both with potentiometric and amperometric techniques, the former showing a wide linear range (1–10 mM), good sensitivity (14.93 ± 0.39 µA cm−2 × mM–1) and a limit of detection (0.32 m‐M). Unlike most metal oxides, it is shown that VOx on glassy carbon is capable of successfully oxidizing glucose at −0.4 V. Such a one‐of‐kind behavior can have important ramifications for energy‐efficient integrated electrochemical sensors and non‐enzymatic glucose sensing as a whole.

“…As a result, a Mg-doping catalyst could be a good way to boost the performance of CuO nanoparticles in photocatalysts. Despite various Mg-doped semiconductors having been described for the damage of organic pollutants, polymer-based nanocomposites for the demolition of organic dyes have attracted a lot of attention [31] because polymers are adjustable in size, shape, chemical structure, ordered nanoparticle assembly, biocompatible, electron promoter, and low in cost [32,33]. To construct the nanocomposites for the dissociation of organic compounds like PVA (polyvinylalcohol) [34,35], chitosan [36,37], and cellulose [33,38,39], a suitable number of natural and synthetic hydrophilic polymeric materials were utilized.…”

“…To construct the nanocomposites for the dissociation of organic compounds like PVA (polyvinylalcohol) [34,35], chitosan [36,37], and cellulose [33,38,39], a suitable number of natural and synthetic hydrophilic polymeric materials were utilized. Among the hydrophilic material, PVA is a hydrophilic polymer that is nontoxic, inexpensive, readily available, and biocompatible, has excellent thermal strength, is water soluble, can produce fine flexible films, and has been described to have noble photocatalytic activity in wastewater management [32,[40][41][42]. As a result, the PVA-modified CuO-Mg composite has outstanding metal-doped metal oxide and polymer properties and so could be a smart, promising composite for effective photocatalysts.…”

Sonochemical synthesis was used to create novel solar light active Mg-doped CuO nanoparticles. Through a chemical impregnation method, the produced nanomaterial was changed with PVA (polyvinylalcohol). The optical properties, crystal structure, and surface morphologies of the synthesized nanomaterials were probed by UV-visible spectroscopy (UV-vis-DRS), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), photoluminescence spectroscopy (PL), thermogravimetric analysis (TGA), and BET specific surface area studies. The prepared nanomaterials were utilized for the photocatalytic destruction of methylene blue (MB). The photocatalytic activity of PVA-modified Mg-doped CuO nanocomposite is magnificent to CuO and Mg-doped CuO nanomaterials. This is because of the remarkable electron-hole dissociation and overwhelming increased photocatalytic activity achieved through surface modification. Additionally, the consequence of several reaction factors like pH, catalyst dosage, and MB concentration was deliberated. This research could lead to the development of polymer-based metal oxide-doped catalysts for the decomposition of organic contaminants in wastewater.
