Special Issue Information

Dear Colleagues,

Membrane science and technologies are a key component for addressing many important issues such as drinking water, energy and elimination of environmental burdens etc. Currently, membranes have become an integral part of industrial processes with considerable commercial and technical importance. Polymeric membranes applications are varied and in recent years have evolved into many fields and are intensively investigated for application in fields such as barrier properties for packaging films; gas separation; water purification processes including nano/micro filtration, reverse osmosis; electrodialysis; dialysis; hemodialysis, and protective coatings (paint). Various emerging technologies employs polymeric membranes such as in secondary batteries and fuel cell applications, several optoelectronic applications, and conductive polymeric coatings and films.

This special issue welcomes articles on different aspects of membrane applications but are not limited to: 

  • Energy storage and generation
  • Electronics
  • Biomedical applications
  • Sensors
  • Separation and water purification techniques
  • Gas or liquid capture
  • Membrane design using Industry 4.0 Technology

A nanofiber mat of styrene−co−vinylbenzyl chloride−co−acrylonitrile copolymer as an anion exchange membrane (AEM) was synthesized via the electrospinning of organic reaction mixtures. The synthesized membranes were characterized using FT-IR spectroscopy for structural analysis. The AEM demonstrated a high ionic conductivity mainly due to the phase segregation in the membrane structure, as analyzed by transmission electron microscopy (TEM). The membrane properties such as water uptake, swelling ratio, and ion exchange capacity, as well as ionic conductivity, varied with the chemical composition. With the molar ratio of styrene, vinylbenzyl chloride, and acrylonitrile at 3:5:2, the highest ionic conductivity of 0.214 S cm−1 at 80 °C was observed. Additionally, the AEM retained 94% of original conductivity after 72 h of soaking in 1 M KOH solution. Full article

The fuel cell industry is the most promising industry in terms of the advancement of clean and safe technologies for sustainable energy generation. The polymer electrolyte membrane fuel cell is divided into two parts: anion exchange membrane fuel cells (AEMFCs) and proton exchange membrane fuel cells (PEMFCs). In the case of PEMFCs, high-power density was secured and research and development for commercialization have made significant progress. However, there are technical limitations and high-cost issues for the use of precious metal catalysts including Pt, the durability of catalysts, bipolar plates, and membranes, and the use of hydrogen to ensure system stability. On the contrary, AEMFCs have been used as low-platinum or non-platinum catalysts and have a low activation energy of oxygen reduction reaction, so many studies have been conducted to find alternatives to overcome the problems of PEMFCs in the last decade. At the core of ensuring the power density of AEMFCs is the anion exchange membrane (AEM) which is less durable and less conductive than the cation exchange membrane. AEMFCs are a promising technology that can solve the high-cost problem of PEMFCs that have reached technological saturation and overcome technical limitations. This review focuses on the various aspects of AEMs for AEMFCs application. Full article
