Ionic liquid mixed matrix membranes (IL3Ms) were synthesized using polyethersulfone (PES) as the base polymer and silica-aluminophosphate (SAPO-34) as the dispersed particles, and their CO2 permeation was investigated. Three of the most widely used models for gas separation—the Maxwell, Lewis–Nielson, and Maxwell–Wagner–Sillar (MWS) models—were then applied to the membranes. Large deviations were found between the model predictions and experimental data. FESEM images suggested that local agglomeration and disorientation of the SAPO-34 particles within the membrane afforded substantial changes in the morphology. The MWS model, which considers the shape factor, was modified to incorporate the volume fraction of the wetted dispersed phase and the ideal shape factor. A direct relationship was found between the filler concentration and the shape factor. The modified model was shown to produce absolute and relative errors of less than 3%. When validated against data from the literature, the deviation remained within 5%. The modified model can be used to estimate the gas permeance of an IL3M.

“…Polyethersulfone (Ultrason® E6020P) (PES) flakes was purchased from BASF, Germany. This polymer was selected as polymer matrix due to its commercial availability and has been successfully used in various applications of gas separation . The PES flakes were dried in an oven at 120°C for 24 h in order to remove the absorbed moisture prior to the dope solution preparation.…”

“…The addition of silane coupling agents were found to reduce the formation of voids around the filler but yet to completely eliminate them . Another approach was reported to include the ionic liquid into MMM formulation which can act as the wetting agent around the zeolite and thus, improve the polymer/SAPO‐34 interaction .

Mixed matrix membranes (MMMs) embedded with functionalized SAPO-34 were successfully synthesized and characterized. Two different types of organic amino cation, namely ethylenediamine (EDA) and hexylamine (HA), were used to functionalize SAPO-34 particles prior to MMM synthesis. In this work, the effects of different functionalizing agents on the membrane morphology, pore size, and CO 2 /CH 4 gas separation properties were investigated. Surface modification of SAPO-34 was confirmed via X-ray photoemission spectroscopy (XPS) where the presence of nitrogen atom was observed for the samples functionalized with amino cations. The dispersion of EDA-functionalized SAPO-34 particles was found to have better polymer/filler interface morphology as shown by field emission scanning electron microscopy (FESEM) analysis. The gas separation performance revealed that PES containing EDAfunctionalized SAPO-34 exhibited better CO 2 /CH 4 separation performance as compared to the MMMs containing HA-functionalized SAPO-34.

“…An ionic liquid has been used to wet both the polymer phase and a zeolite (SAPO-34) for selective gas separations. [66][67][68] Another method is to perform the casting on a dense liquid surface with high surface tension in order to avoid strong membrane adhesion to the casting substrate surface. 14 Herein, the polymer solution can contract freely after casting and the stresses distribute uniformly in every direction and forms void-free membranes.…”

Mixed matrix membranes (MMMs) have gained lot of interest in the research community over the last few years in order to overcome the performance trade-off shown by the polymeric membranes. An MMM utilizes the benefits of both polymeric and inorganic materials and has the potential to show very high performance without much increase in the cost of fabrication. But the fabrication of an MMM without conceding the mechanical properties is very challenging. In this chapter, the materials selection and fabrication techniques of MMM in both flat sheet and hollow fiber configurations are discussed. Formation of defects at the interface is one of the biggest challenges in fabricating the MMM. Different techniques used in the literature to compatibilize the polymer and particle were summarized. In addition, the recent progress of MMM for gas separation applications and performance prediction models were provided in detail.
