Abstract
En 中文
• PPSU, PSU, PES and PBI membranes were compared for H2 separation and CO2 capture. • PPSU shows the best CO2/N2 performance among sulfone-based polymers. • Larger d-spacing and FFV contribute to the high CO2 permeability of PPSU. • PES favors H2/N2 and H2/CO2 separations due to tighter chain packing. • Structure–property relationships guide the selection of scalable polymers.
