Mixed matrix membranes (MMMs) composed of a glassy polymer (polysulfone) and the flexible metal organic framework NH(2)-MIL-53(Al) exhibit excellent separation properties. In contrast to most reported membranes, CO(2)/CH(4) separation selectivity increases with pressure, related to the flexibility of the filler.

Mixed matrix membranes (MMMs) are attracting significant interest for pervaporation and gas separation applications. To better comprehend the impact of filler particles within polymer matrices, the species permeation mass transport was theoretically studied by numerical simulation using finite differences. The Fick’s second law of diffusion was solved for a three-dimensional MMM to obtain the c...

Air separation is one of the most challenging separations because very similar molecular dimensions gas molecules. We used a high-throughput computational screening approach to identify upper performance limits metal organic framework (MOF) membranes and MOF/polymer mixed matrix (MMMs) for O2/N2 separation. Gas permeabilities selectivities were calculated 5629 MOF 78,806 different types MMMs, w...

Multiple Model Methodologies (MMM) have become ubiquitous in the area of conceptual modeling. Thus, the Unified Modeling Language (UML) is a popular MMM in software engineering, while MMMs are also used in enterprise modeling. Over the last few years, the size problem domains being modeled by MMMs has also grown. Thus, software is now bigger, and enterprises are significantly larger in scale th...

Zeolitic imidazolate frameworks (ZIFs), a subclass of metal–organic (MOFs), have been widely investigated as additive in mixed matrix membranes (MMMs), but systematic studies to identify critical intrinsic ZIF-type parameters that determine the MMM performance are lacking. Therefore, three isoreticular gmelinite (GME) ZIFs, i.e., ZIF-68, 69 and 78 distinct by their partial different linkers, we...

Mixed matrix membranes (MMMs) consisting of fillers (e.g. metal organic frameworks (MOFs)) in polymer are considered as an interesting alternative for capturing post combustion CO2 towards a sustainable development. This research is focused on the recycling MMMs made Pebax® 1657 and MOF ZIF-94. Upon MMM preparation, characterization testing, were dissolved to recover MOFs separately. Recovered ...

Confinement of crystals metal–organic frameworks (MOFs) in polymers to form MOF/polymer mixed-matrix membranes (MMMs) can lead changes intra-MOF diffusion. Such diffusion were previously demonstrated for light gases, and attributed a reduction MOF framework flexibility. However, our knowledge, no direct measurements MMMs the related confinement effect on have been reported organic liquids. In t...

It is still a great challenge to prepare high performance mixed matrix membranes (MMMs) because of the difficulty in finely tuning the compatibility between filler and organic phases. In this work, ZIF-8 nanoparticles hydrophobically functionalized by 5, 6-dimethylbenzimidazole (DMBIM) via shell ligand exchange (SLE) reaction were incorporated into polydimethylsiloxane (PDMS) matrix to fabricat...

Increasing the hydrophobicity of membrane was believed as an effective approach to enhance the performance of organophilic pervaporation (PV) membrane. In this work, the superhydrophobic alkyl group modificated metal organic framework (MOF) of RHO-[Zn(eim)2] (MAF-6) was incorporated into polydimethylsiloxane (PDMS) polymer to fabricate mixed matrix membranes (MMMs). The morphologies, physical a...

This is a comprehensive review of the recent progresses made in the field of zeolite membranes. It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs)....
