摘要：

Membranes containing polyether segments may exhibit high CO2/N2 separation performance due to strong affinity between polyether segments and CO2. Membranes with ethylene oxide (EO) groups are widely investigated, but high crystallinity of membranes with EO groups reduces gas permeance of membranes. Compared with EO group, propylene oxide (PO) group possesses an additional side methyl group that prevents crystallization and increases free volume of the membrane, which promotes gas permeance of the membrane. However, preparation of the composite membrane containing PO groups is rarely reported. In this work, composite membranes containing PO groups were prepared by interfacial polymerization with trimesoyl chloride and polyetheramines containing PO groups. The effects of PO group content and degree of cross-linking on separation performance of the membrane were investigated by using D400, D230 or T403 as the monomer in the aqueous phase. The membrane prepared with D400 exhibited the highest CO2 permeance and CO2/N2 selectivity due to its high PO group content and low degree of cross-linking. Moreover, the effects of monomer concentration, acid acceptor, and pH of the aqueous phase on separation performance of the membranes were also investigated. The high-performance membrane containing PO groups was prepared by optimizing the preparation conditions. ©All Rights Reserved.
