About this Research Topic
One of the foremost problems faced by the current world is air and water pollution due to the operations involved to meet the growing energy demand. Polymeric membranes provide a promising alternative solution to the conventional separation technologies owing to their unique features such as high energy efficiency, less environmental footprint and low cost. They are widely and commercially used in a range of industrial applications, such as gas separations - mainly CO2 capture from powerplants-, bio-alcohol upgrading, natural gas purification, biogas upgrading, and so on. Despite their many advantages, polymeric membranes face certain limitations that hinder their wide-scale industrial applications. There is an urgent need to design membrane materials that facilitate the commercialization of membranes.
The trade-off between permeability and selectivity is one of the challenges faced by membrane researchers. Concentration polarization, thermal and chemical stability, fouling, and long-term operations are few more examples of limitations faced by polymeric membranes. This has led membrane researchers to make attempts and address the shortcomings of polymeric membranes through several strategies, for instance (1) tailoring the membrane material for desired application, (2) embedding porous inorganic fillers in polymer matrix to fabricate mixed matrix membranes 3) post-treatment of membranes by chemical cross-linking, functionalization, thermal annealing etc.
This Research Topic will focus on the development of emerging membrane materials, tuning of membranes for desired applications, and their practical implementation to accelerate the development of advanced polymeric membranes for clean and sustainable energy production. The applications of the synthesized membranes will include but not be limited to biogas and natural gas upgradation, bio-alcohols purification, wastewater treatment, CO2 capture from powerplants and so on.
