چکیده انگلیسی
In this study, gas separation properties of Matrimid/MIL-53 mixed matrix membranes with different MOF weight percentages (0-20Â wt.%) were investigated. TEM, XRD and DLS analysis were implemented to investigate MIL-53, structure and particles size distribution. SEM, FTIR, DSC and TGA analyses were conducted to characterize the fabricated membranes. The SEM images of these membranes showed good adhesion between polymer and particles, although for 20% MIL-53 loading, particles agglomeration was observed in some areas. Moreover, surface images of the membranes showed adequate dispersion of the particles in the polymer matrix, especially at lower MOF loadings. The permeability of pure CO2 and CH4 gases for all membranes were measured and the ideal CO2/CH4 selectivity was calculated. CH4 permeability of membranes increased slightly as the percentage of loading increased. At 20Â wt.% MOF loading, void formation led to a significant increase in CH4 permeability (300% over pure Matrimid). CO2 permeability showed the same trend; there was a 94% increase in permeability compared to pure Matrimid for 15Â wt.% MMMs. CO2/CH4 selectivity also increased as MOF loading increased. The highest selectivity was shown for 15Â wt.% MOF loading. This membrane had 84% growth in selectivity over pure Matrimid. Although at 20Â wt.% MIL-53 loading, membrane separation performance was destroyed.
