“…This BTDA-DAPI, also known as Matrimid R 5218, is a commercialized PI obtained by polycondensation polymerization of 3,3 ′ ,4,4 ′ -benzophenone tetracarboxylic dianhydride (BTDA) and a mixture of two cycloaliphatic monomers such as 5,6-amino-1-(4 ′ -aminophenyl)-1,3,3trimethylindane, producing BTDA-DAPI (Guiver et al, 2002). Thanks to its high chemical resistance, excellent adhesion, high solubility in many organic solvents, and good thermal stability (T g around 305-315 • C), Matrimid R is so far the most explored polymer for GS (Castro-Muñoz et al, 2018d) and some other applications in the membrane technology area, such as ultrafiltration (Russo et al, 2019), pervaporation (Castro-Muñoz et al, 2018a, 2019b, and membrane distillation (Xu et al, 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.

“…However, Matrimid does not show high productivity in terms of permeate flux (permeability). Recent research and development are focused on enhancement of this polymer in terms of CO 2 permeability, whereby its blending with several polymers and additives has been proposed . This is the case for polyethylene glycol (PEG), which has demonstrated enhancement of CO 2 permeability in polymer membranes , .…”

The effect of CO 2 -philic additive polyethylene glycol (PEG) 200 in Matrimid 5218 on the separation performance of prepared membranes was evaluated in a binary gas mixture. Matrimid/PEG 200 flat-sheet blended membranes with low PEG concentrations were prepared by the dense film-casting method. Pure Matrimid and blended membranes were characterized by FTIR spectroscopy, scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and permeation measurements. The addition of 4-5 % of PEG enhanced considerably the CO 2 permeability of the Matrimid matrix. The best formulation, Matrimid/PEG 200 (96/4), showed in comparison to pure Matrimid a more than threefold increase in CO 2 permeability and an increase in separation factor of about 40 %.

“…8,10 Thereby, starting from the known separation features of the pristine polymers, several design concepts of new membranes have been developed, including cross-linked, polymer blending, annealed, composite, asymmetric and mixed matrix membranes (MMMs), 11 and MMMs based on the copolymerization of organic macrocyclic molecules and microporous polymers. [12][13][14][15][16][17] Among these types of membranes, the research community is looking for those involving nanostructured (inorganic, organic, or hybrid) materials, which once combined with polymer materials tend to result in a synergistic performance by combining the strengths of organic and inorganic materials. Nowadays, MMMs are likely the most explored membranes, oen as a proof of concept for new porous llers.…”
