Published: April 17, 2025

Abstract To mitigate global climate change, the development of membranes with high CO 2 permeability and selectivity is urgently needed. Here, a simple effective non‐solvent‐induced microstructure rearrangement (MSR) technique proposed to enhance gas separation performance Pebax 2533 membranes. By immersing in amino acid salt solutions induce MSR, optimized 2533‐GlyK 10 wt.% membrane reached 1180 Barrer, 4.5‐fold increase compared original membrane, without compromising /N selectivity. Moreover, MSR maintains stable for nearly 500 days, demonstrating excellent long‐term stability. Furthermore, applying thin‐film composite (TFC) revealed that both 2533/polyvinyl chloride (PVC) hollow fiber (HF) TFC 2533/polyacrylonitrile (PAN) flat‐sheet exhibited significantly enhanced permeance under treatment DI water. Characterization results indicated chemical‐physical properties before after are unchanged, suggesting promising next‐generation carbon capture.
