“…To improve on gas separation properties, the concept of mixed matrix membranes (MMM) was developed in the last two decades to overcome some limitations of polymer membranes. In fact, MMMs combine the processability of the polymer phase with superior transport properties of an inorganic phase (small particles) resulting in a combination of the advantages of both materials . Different types of inorganic particles such as zeolites, carbon molecular sieves, and inorganic oxides, have been used to prepare MMM.…”

CuBTC and NH2‐CuBTC metal organic frameworks (MOF) were used to produce mixed matrix membranes (MMM) with a block copolymer of poly(ether‐b‐amide‐6) (Pebax® MH 1657) as the polymer matrix to investigate the effect of amine functionalized group (–NH2) on the CO2/CH4 gas separation performance of the MMM. The MOF were fully characterized by XRD, FTIR‐ATR, TGA, N2, CO2, and CH4 adsorption, while the MMM were characterized using FTIR‐ATR, TGA, DSC, and SEM. Permeability and selectivity of the MMM were studied at different MOF mass contents (5 to 20 g/g) and feed pressures (0.3 to 1.5 MPa) for pure and mixed gases. The CO2 permeability for 20 g/g of both Pebax/CuBTC and Pebax/NH2‐CuBTC MMMs was nearly twice that of the neat polymeric membrane, while the presence of amine functionalized group in NH2‐CuBTC produced an increasing trend of CO2/CH4 ideal selectivity at high NH2‐CuBTC loading and about a 60 % increase was observed at 20 g/g of NH2‐CuBTC.

“…Adding adsorptive materials to polymeric matrices to generate mixed‐matrix membranes (MMMs) has been investigated since 1987. Fillers embedded in polymer matrices can improve the performance of membranes compared to neat polymeric materials since this type of membranes combines the process ability of polymers with good transport properties of fillers , .…”

Chitosan/ZIF‐8 Mixed‐Matrix Membranes for Pervaporation Dehydration of Isopropanol

2017

Zeolitic imidazolate frameworks (ZIF-8) nanoparticles were successfully synthesized and embedded into a chitosan (CS) polymeric matrix to prepare CS/ZIF-8 mixed-matrix membranes (MMMs) in order to investigate the effect of ZIF-8 addition as novel filler on the dehydration performance of the CS polymeric membrane. MMMs were evaluated using pervaporation (PV) dehydration of isopropanol (IPA). The synthesized ZIF-8 nanoparticles and MMMs were characterized by X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and a swelling study. The PV performance of the prepared MMMs with different ZIF-8 loadings for IPA dehydration was investigated. For the ZIF-8/CS MMMs, at the optimum loading the total flux increases significantly with low separation factor reduction. The good PV performance of the ZIF-8-incorporated CS membranes for dehydration of IPA is demonstrated.

“…This therefore demonstrates the importance of understanding the porosity of the inorganic filler and how it will affect the alcohol/water separation to be achieved. Therefore there have been many other investigations into the performance of different zeolites and aluminosilicates within MMMs for dehydration of organic-aqueous mixtures [ 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 ].…”

Hybrid and Mixed Matrix Membranes for Separations from Fermentations

2016

View full text Add to dashboard Cite

Fermentations provide an alternative to fossil fuels for accessing a number of biofuel and chemical products from a variety of renewable and waste substrates. The recovery of these dilute fermentation products from the broth, however, can be incredibly energy intensive as a distillation process is generally involved and creates a barrier to commercialization. Membrane processes can provide a low energy aid/alternative for recovering these dilute fermentation products and reduce production costs. For these types of separations many current polymeric and inorganic membranes suffer from poor selectivity and high cost respectively. This paper reviews work in the production of novel mixed-matrix membranes (MMMs) for fermentative separations and those applicable to these separations. These membranes combine a trade-off of low-cost and processability of polymer membranes with the high selectivity of inorganic membranes. Work within the fields of nanofiltration, reverse osmosis and pervaporation has been discussed. The review shows that MMMs are currently providing some of the most high-performing membranes for these separations, with three areas for improvement identified: Further characterization and optimization of inorganic phase(s), Greater understanding of the compatibility between the polymer and inorganic phase(s), Improved methods for homogeneously dispersing the inorganic phase.
