Abstract
This paper synthesized a new mixed matrix membrane for CO2 separation. First, the metal-organic framework UIO-66 was treated with air plasma for modification and then embedded in Pebax® 1657. The 10% UIO-66/Pebax® 1657 mixed matrix membranes treated with air plasma significantly improved interfacial compatibility and CO2 adsorption capacity, showing excellent performance. Its permeability reached 453 Barrer as CO2 and the selectivity was 37.8 as CO2/N2. It was confirmed by characterization techniques such as FTIR, XRD, XPS, TGA, NMR, and SEM that the plasma successfully introduced ─NH2 groups and active sites on the UIO-66 surface, thereby significantly improving the interfacial compatibility and adsorption characteristics of the mixed matrix membrane. In this study, the high-performance CO2 separation membrane aP-UIO-66/Pebax was innovatively enhanced through the synergistic effects of graft modification and defect engineering on UIO-66 using nonthermal plasma technology. This approach offers a novel strategy for membrane performance optimization.
