Abstract

Gas separation has changed over the last few decades with membrane technology emerging as an important player. Polysulfone is considered an interesting material for gas separation membrane applications mainly due to its good thermal and chemical stability and excellent mechanical strength at a low cost. This review presents a comprehensive discussion on the advancements acheived in the development of polysulfone-based membranes for gas separation. It focuses on various strategies that have been reported to enhance the performance of these membrane materials, including filler incorporation, polymer blending and the addition or chemical modification of functional groups that confer specific adaptability to the polymers.
