Membranes have shown immense potential for ensuring high selectivity and permeability. Mixed matrix membranes (MMMs) composed of inorganic fillers dispersed in a polymer matrix are considered an effective solution for overcoming the trade-off-related limit. However, despite their high separation performance, MMMs often exhibit non-selective interfacial defects formed by poor interactions between the filler and the polymer matrix. The preparation of composite MMMs in a thin film form, which is a highly preferred configuration for commercialization, is also challenging in most cases. Furthermore, the cost of inorganic materials is generally higher than that of organic polymers. I will talk about our recent studies on dual-phase, all-polymeric membranes that exhibit simultaneous improvements in CO2 permeability and CO2/N2 selectivity based on a graft copolymer filler. |
