Summary: Introducing CO2 affinity additives into membranes is an effective method to enhance CO2 permeability for natural gas sweetening. In this study, high performance mixed-matrix membranes were successfully prepared using cellulose acetate (CA) as the matrix and zeolitic tetrazolate-imidazolate frameworks (ZTIFs) with high CO2 affinity as the additive. The interaction between CA matrix and ZTIFs was confirmed by FT-IR. The morphology properties of the membranes were evaluated using SEM, EDS, and XRD. The CO2 permeability of CA/ZTIFs mixed-matrix membranes, which depended on the loading of high CO2 affinity ZTIF additive, ranged from 9.59 to 15.85 Barrer, indicating the significant role of ZTIFs in altering CO2 dissolution and diffusion behavior inside the membranes. The ideal compatibility and gas selectivity highlight the promising potential of ZTIFs additives in gas separation applications.

Summary: This study investigated the permeation characteristics of CA/γ-CD-MOF mixed matrix membranes for CO2/CH4 separation, with defect-free membranes showing uniform dispersion of filler and high selectivity. Increasing filler weight percentage and pressure led to decreased permeability and selectivity for both gases, with the highest CO2/CH4 selectivity achieved by CA/γ-CD-MOF 0.4wt% MMM.

Summary: This study investigates the impact of crown-ether ring size and rigidity on the gas separation performance and plasticization behavior of Matrimid (R) 5218 polyimide membranes. The crown-ether containing membranes exhibit enhanced solubility selectivity for CO2 but reduced solubility and permeability for both CO2 and N-2. The variation in crown-ether size and rigidity does not significantly affect the plasticization resistance of the membranes.

Summary: As a new type of porous materials, metal-organic cages (MOCs) have great potential in adsorption and separation. In this study, a series of zirconocene-based MOCs were used to fabricate MMMs with polyimide 6FDA-DAM, and the MOC-1-4F based membranes showed improved gas separation performance compared to other MOC-based membranes. The introduction of MOC-1-4F promoted the Tg values, mechanical property, CO2 solubility, and diffusivity of the membrane. The low-loaded MOC-1-4F MMM exhibited significantly improved CO2 permeability and selectivity for CO2/CH4 separation.

Summary: Plasticized cellulose acetate is a widely used bio-based polymer that requires the addition of plasticizers for improved workability and thermal-mechanical properties. However, plasticizers can migrate, causing the material to become brittle or crack. Designing new plasticizers can help reduce material degradation.

Summary: This study investigates enhancing the separation performance of cellulose acetate (CA) by incorporating ionic liquid-like pendants. The experiments show that with increasing HEDMA content, the permeability of CO2 and N-2 decreases, while the selectivity of CO2/N-2 initially decreases and then gradually increases. This suggests potential for further improvements by altering interactions between the polymer network and permeating CO2 molecules.

Summary: In this study, Ultem and NaX zeolite were used to fabricate mixed matrix membranes for CO2 separation. The optimized MMM exhibited a CO2/N-2 selectivity of 34 and a 45% increase in CO2 permeability compared to the pristine membrane. These improvements were attributed to the surface diffusion mechanism of zeolite X and the reversible reaction between Ni2+ ions and CO2 molecules.

Summary: Water supply requirements in this century are a significant challenge facing humanity, and membrane technology, specifically electrospun polymer nanofibers, are being developed as promising engineered materials for water treatment due to their high porosity, permeate flux, selectivity, and stability. Mixed matrix electrospun nanofibrous membranes (mixed matrix ENMs) have gained attention for water desalination and ion removal due to their designed pore size, surface chemistry, hydrophobicity/hydrophilicity, porosity control, increased flux, and rejection efficiency. This review provides insights for using mixed matrix ENMs for desalination and emphasizes sustainable development for future research.

Summary: In this study, metakaolin-based geopolymer was obtained by activating metakaolin with an alkali activator containing silica fume and sodium hydroxide. The addition of silica fume and adjustment of Na2O/Al2O3 molar ratio resulted in the formation of geopolymer-zeolite composites, which exhibited higher compressive strength. The presence of large zeolite crystals in the geopolymer matrix was observed in the composite with 10 wt% silica fume and a Na2O/Al2O3 molar ratio of 1. The maximum compressive strength was achieved at 15 wt% silica fume, Na2O/Al2O3 molar ratio of 1, and curing temperature of 70 degrees C.

Summary: This study fabricated novel dense membranes by blending Pebax with PAMAM and evaluated their application in CO2/CH4 gas separation. The results showed that PAMAM loading, operating pressure, and temperature significantly affected gas permeability and CO2/CH4 selectivity. Gas permeability in the membranes was primarily governed by gas solubility rather than diffusivity. Modifying Pebax membrane with PAMAM improved separation performance with minimal aging and good stability.

Summary: Methane, the main gaseous fuel, can be obtained from natural gas or biogas. Upgrading these gases by separating impurities like CO2, N2, H2S, O2, CO, NH3, H2O, and heavier hydrocarbons is important. Membrane separation technology is an attractive method for upgrading, and 6FDA-based polyimides and PIM membranes with mixed matrix (MOFs, zeolites, and POFs) have shown the best performance. However, polymeric membranes are susceptible to chemical and physical changes due to CO2 plasticizing effect, which can be prevented by crosslinking and heat annealing.
