“…When dealing with the membrane materials, polymers are the most likely explored and used, in which many types of polymers have been considered including polymers of intrinsic microporosity (PIMs), polysulfones, cellulose acetates, poly(2,6-dimethyl-1,4-phenylene oxide) (PPO), aramids (aromatic polyamides), polycarbonates, and polyimides (PIs) (Robeson, 1991;Visser et al, 2007;Sanders et al, 2013). At this point, PIs have been the most studied, well-established, and commercialized category of polymers (Sanaeepur et al, 2019). PIs are high-temperature engineered polymers, initially developed by DuPont TM (McKeen, 2012).…”

Several concepts of membranes have emerged, aiming at the enhancement of separation performance, as well as some other physicochemical properties, of the existing membrane materials. One of these concepts is the well-known mixed matrix membranes (MMMs), which combine the features of inorganic (e.g., zeolites, metal-organic frameworks, graphene, and carbon-based materials) and polymeric (e.g., polyimides, polymers of intrinsic microporosity, polysulfone, and cellulose acetate) materials. To date, it is likely that such a concept has been widely explored and developed toward low-permeability polyimides for gas separation, such as oxydianiline (ODA), tetracarboxylic dianhydride-diaminophenylindane (BTDA-DAPI), m-phenylenediamine (m-PDA), and hydroxybenzoic acid (HBA). When dealing with the gas separation performance of polyimide-based MMMs, these membranes tend to display some deficiency according to the poor polyimide-filler compatibility, which has promoted the tuning of chemical properties of those filling materials. This approach has indeed enhanced the polymer-filler interfaces, providing synergic MMMs with superior gas separation performance. Herein, the goal of this review paper is to give a critical overview of the current insights in fabricating MMMs based on chemically modified filling nanomaterials and low-permeability polyimides for selective gas separation. Special interest has been paid to the chemical modification protocols of the fillers (including good filler dispersion) and thus the relevant experimental results provoked by such approaches. Moreover, some principles, as well as the main drawbacks, occurring during the MMM preparation are also given.

“…Additionally, it can be concluded that as the dominant permeation mechanism in polymeric membranes is solution‐diffusion, permeability changes for low permeable gases such as CH 4 , N 2 , and O 2 confirmed that permeability enhancement is mainly affected by diffusion coefficient improvement. Embedding the porous zeolite particles into the polymers matrix directly affect the diffusion of penetrants.…”

In this paper, a novel comprehensive permeation model for mixed matrix membranes (MMMs) is introduced. This model shows the importance of understanding and developing a more reliable model for the permeation behavior of MMMs containing porous filler nanoparticles. A new method is established to provide a more precise/large‐scale three‐dimensional MMMs geometry. The required number of spherical porous fillers in random/nonuniform positions in the polymer matrix is calculated. Interfacial equilibrium constant (K) at the polymer/filler interfaces was adjusted as the concentration ratio of the diffusing penetrants (C2 and C1) at the interface, respectively. In this case, the K values are changed by varying the intended gaseous concentration due to their permeation through the MMM. Hence, its effect on penetrants effective diffusion coefficient was examined. Then, the obtained results were evaluated with similar experimental data, which showed much consistency. Therefore, the accurate calculation method for MMMs permeability was governed for the entire range of the operating pressures in MMMs. The results showed that the permeability of MMMs increases with increasing filler particle size. On the other hand, variations that occur in the MMM permeability at various particle size were much more distinct at higher loadings. Moreover, some well‐known analytical permeation models were used to compare and validate the model's permeability results. It can be concluded that this model provides a method for more precise and realistic design of MMMs as well as to better construe the large number of related experimental data. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Recent years have witnessed a rapid growth in the great-scale adoption of membrane technology due to its intrinsic merits of energy saving, easy operation, scalability, and small carbon footprint. [1] Membranes that can selectively transport molecules and ions are imperative in these applications, such as gas separation, water treatment, energy conversion and storage, etc. However, synthetic membranes always suffer from the trade-off between permeability and selectivity.…”

Hydrophilic Microporous Polymer Membranes: Synthesis and Applications

et al. 2020

Ion and water transfer in subnanometer‐sized confined channels of hydrophilic microporous polymer membranes show enormous potential in tackling the ubiquitous trade‐off between permeability and selectivity for energy and environment‐related membrane technologies. To this end, a variety of hydrophilic polymers of intrinsic microporosity (HPIMs) have been developed. Herein, the synthetic strategies toward HPIMs are summarized, including post‐synthetic modification of polymers to introduce polar groups (e. g., amines, hydroxy groups, carboxylic acids, tetrazoles) or charged moieties (e. g., quaternary ammonium salts, sulfonic acids), and the polymerization of hydrophilic monomers. The advantages of HPIM membranes over others when employed in energy conversion and storage, acid gas capture and separation, ionic diodes, and ultrafiltration, are highlighted.
