摘要
Asymmetric mixed-matrix membranes (MMMs) were prepared via phase inversion from Matrimid® or Matrimid®/Polysulphone blends containing a crystalline metal organic framework (MOF: [Cu3(BTC)2]) to improve the membrane gas separation performance. Physical properties of the synthesized MOF and the membrane (film density, Tg, d-spacing) were analyzed. The distribution of MOF embedded in the polymer was studied with SEM. Improvement in thermal and mechanical properties of membranes with increasing [Cu3(BTC)2] loadings, as well as increasing CO2/CH4 and CO2/N2 selectivity and permeance of the silicone sealed membranes suggests defect-free membranes with good compatibility at the filler/polymer interface. Also, relative permeance was in accordance with the Maxwell model for porous materials.
