“…The CO 2 /N 2 selectivity and CO 2 permeance were increased to 44.9 and 7.19 GPU, respectively, with 5 wt.% of filler loading at 3.5 Bar and 30 °C [ 77 ]. Shindo et al also studied the effect of adding ionic liquid ([C4mim][Tf2N]) to an MMM containing 6FDA-TeMPD polyimide and zeolite ZSM-5 [ 70 ]. It was evident that with the addition of IL, the interfacial voids were reduced, with a consequentially improved CO 2 selectivity against both N 2 and H 2 [ 78 ].…”

“…Zhang et al reported a tertiary-component MMM based on doping Pebax polymer with PEG-600 and NaY zeolite.The MMMs with 20 wt.% PEG and 30 wt.% NaY zeolite showed CO2/N2 selectivity of 107.9 and CO2 permeability of 172.6 Barrer. Furthermore, with the CO2/N2 mixed gas, the designed membrane could directly enrich the concentration of CO2 from 15% to 96.7% in one step[70].…”

Since the second industrial revolution, the use of fossil fuels has been powering the advance of human society. However, the surge in carbon dioxide (CO2) emissions has raised unsettling concerns about global warming and its consequences. Membrane separation technologies have emerged as one of the major carbon reduction approaches because they are less energy-intensive and more environmentally friendly compared to other separation techniques. Compared to pure polymeric membranes, mixed matrix membranes (MMMs) that encompass both a polymeric matrix and molecular sieving fillers have received tremendous attention, as they have the potential to combine the advantages of both polymers and molecular sieves, while cancelling out each other’s drawbacks. In this review, we will discuss recent advances in the development of MMMs for CO2 separation. We will discuss general mechanisms of CO2 separation in an MMM, and then compare the performances of MMMs that are based on zeolite, MOF, metal oxide nanoparticles and nanocarbons, with an emphasis on the materials’ preparation methods and their chemistries. As the field is advancing fast, we will particularly focus on examples from the last 5 years, in order to provide the most up-to-date overview in this area.

“…Pebax-based MMMs were fabricated by incorporating cage-type zeolites at high loadings (NaY, 10–40 wt% [ 57 ]; NaY and poly(ethylene glycol), 30 wt% [ 58 ]) and –COOH surface-functionalized NaX nanozeolites at low loadings (up to 1.5 wt%) [ 59 ]. NaX nano-fillers incorporated into the PEBA polymer (up to 2 wt%) were also used to prepare composite MMMs on a polyethersulfone support, displaying interesting gain in the CO 2 /N 2 selectivity compared to nonporous SiO 2 nanofillers [ 15 ].…”

“…Poly(ethylene glycols) (PEGs) were used in blends with the Pebax matrix in different works [ 27 , 36 , 47 , 58 , 73 , 92 ] since they are known to significantly increase the permeability of Pebax [ 112 ], while keeping the CO 2 /N 2 selectivity [ 47 ]. A plasticizing effect with a significant reduction in the crystallinity of the PA phase was reported upon the addition of PEG-MEA to Pebax 1657 [ 45 ].…”

An inspiring challenge for membrane scientists is to exceed the current materials’ performance while keeping the intrinsic processability of the polymers. Nanocomposites, as mixed-matrix membranes, represent a practicable response to this strongly felt need, since they combine the superior properties of inorganic fillers with the easy handling of the polymers. In the global strategy of containing the greenhouse effect by pursuing a model of sustainable growth, separations involving CO2 are some of the most pressing topics due to their implications in flue gas emission and natural gas upgrading. For this purpose, Pebax copolymers are being actively studied by virtue of a macromolecular structure that comprises specific groups that are capable of interacting with CO2, facilitating its transport with respect to other gas species. Interestingly, these copolymers show a high versatility in the incorporation of nanofillers, as proved by the large number of papers describing nanocomposite membranes based on Pebax for the separation of CO2. Since the field is advancing fast, this review will focus on the most recent progress (from the last 5 years), in order to provide the most up-to-date overview in this area. The most recent approaches for developing Pebax-based mixed-matrix membranes will be discussed, evidencing the most promising filler materials and analyzing the key-factors and the main aspects that are relevant in terms of achieving the best effectiveness of these multifaceted membranes for the development of innovative devices.

Mixed matrix membranes (MMMs) were prepared by solvent evaporation method using Pebax‐1074 polymer as matrix and inorganic zeolite SAPO‐23 as dopant. The morphology, surface functional groups, microstructure, thermal stability, and separation performance of MMMs were analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X‐ray diffraction, thermogravimetric analysis, and gas permeation, respectively. The effects of dopant loading amount, permeation temperature, and permeation pressure on the structure and properties of MMMs were investigated. The results showed that the introduction of SAPO zeolite reduced the crystallinity of the MMMs and improved the CO2/N2 selectivity. Under the conditions of 30°C and 0.15 MPa, the MMMs prepared by incorporating with 5% SAPO zeolite in content exhibited the highest CO2/N2 selectivity of 72.0 together with the CO2 permeability of 98.2 Barrer.
