Polyurethane-Based Blend Membrane Containing Polycarbonate for Gas Separation: Compatibility Analysis, Microstructure Evaluation, and CO2 Separation Performance

“…The gas separation (GS) membranes can be prepared from polymers, including polysulfone (PSf), poly-(ether sulfone) (PES), polyurethane (PU), polycarbonate (PC), polyamide (PA), polyimide (PI), poly(ether imide) (PEI), polydimethylsiloxane (PDMS), and polyether-blockamide (PEBA). 5,6 PU, being a versatile family of polymers, has been utilized in various fields, such as construction, automobile, healthcare, and fabric industries, due to the versatility of its properties and synthesis methods. 7−9 Thermoplastic polyurethane (TPU) is a type of plastic PU that involves a block copolymer consisting of alternating sequences of hard and soft segments.…”

“…Despite the wide variety of polymeric materials, few of them can be used to fabricate polymeric membranes due to limitations such as the preparation of a defect-free thin film, difficult processability, and lack of appropriate mechanical and chemical stability. The gas separation (GS) membranes can be prepared from polymers, including polysulfone (PSf), poly­(ether sulfone) (PES), polyurethane (PU), polycarbonate (PC), polyamide (PA), polyimide (PI), poly­(ether imide) (PEI), polydimethylsiloxane (PDMS), and polyether- block -amide (PEBA). , PU, being a versatile family of polymers, has been utilized in various fields, such as construction, automobile, healthcare, and fabric industries, due to the versatility of its properties and synthesis methods. − Thermoplastic polyurethane (TPU) is a type of plastic PU that involves a block copolymer consisting of alternating sequences of hard and soft segments . These segments are formed by the reaction of diisocyanates with diols.…”

Polyimide blend metal–organic framework‐based mixed matrix membrane for gas separation: A review

“…Different from the conventional energy‐intensive gas separation techniques such as amine absorption, 1 cryogenic distillation, 2 and pressure swing adsorption, 3 membrane technology stands out as a superior candidate. Indeed, membrane separation technology offers several benefits such as simplicity in operation, environmental friendly, ease of scaling up, compact size, low maintenance required, and most importantly, cost‐effectiveness 4–6 . Recently, the membrane has appeared as a potential separation process for industrial applications, for instance, natural gas purification, hydrogen recovery, and carbon dioxide removal.…”
