Special Issue Information

Dear Colleagues,

Hydrogels are crosslinked, three-dimensional networks of highly hydrophilic polymers capable of absorbing significant amounts of water or biological fluids. Natural-polymer-based hydrogels contain starch, chitosan, cellulose, alginate, guar gum, and hyaluronic acid, and they are extensively used in biomedical applications such as tissue regeneration and drug delivery. Synthetic polymer hydrogels (such as polyacrylamide and polyethylene glycol) are made using different routes such as bulk polymerization, the free radical mechanism, the radiation method, and solution mixing and casting, leading to enhanced mechanical properties, swelling, stimuli sensitivity, and compatibility in biomedical as well as other engineering applications. Extensive research is being carried out on functionalized hydrogels and their state-of-the-art synthesis methods that have extensive applications in regenerative medicine, separation processes, enhanced oil recovery, and water and wastewater treatment processes.

This Special Issue on “Advances in Synthesis, Testing, and Applications of Natural and Synthetic Polymer Hydrogels” gives the scientific community a chance to present their research findings or provide an update on the discovery of novel polymer hydrogels, their manufacturing methods, and analytical methods for their characterization and applications.

Research articles, as well as reviews, are welcome.

Fuel cell technology is at the forefront of sustainable energy solutions, and polyvinyl alcohol (PVA) membranes play an important role in improving performance. This article thoroughly investigates the various varieties of PVA membranes, their production processes, and the numerous modification tactics used to solve inherent problems. Various methods were investigated, including chemical changes, composite blending, and the introduction of nanocomposites. The factors impacting PVA membranes, such as proton conductivity, thermal stability, and selectivity, were investigated to provide comprehensive knowledge. By combining various research threads, this review aims to completely investigate the current state of PVA membranes in fuel cell applications, providing significant insights for both academic researchers and industry practitioners interested in efficient and sustainable energy conversion technologies. The transition from traditional materials such as Nafion to PVA membranes has been prompted by limitations associated with the former, such as complex synthesis procedures, reduced ionic conductivity at elevated temperatures, and prohibitively high costs, which have hampered their widespread adoption. As a result, modern research efforts are increasingly focused on the creation of alternative membranes that can compete with conventional technical efficacy and economic viability in the context of fuel cell technologies.
