“…However, an introduction of silicalite-1 crystals with smaller free volume than PIM-1 decreased the gas permeability. CO 2 permeability of mixed matrix membrane with silicalite-1 was reduced from 4,390 Barrers to 2,530 Barrers, but gas selectivity was improved [206].…”

“…Various diamine monomers such as Ethylenediamine (EDA), Triethylenetetramine (TETA), and 1,4-diaminobutane (BuDA) were used and cross-linking time was also controlled. PIM-1/Matrimid (90:10) blend membranes cross-with inorganic materials, so-called mixed matrix membranes (MMM), have been investigated with various materials such as silica nanoparticle, zeolite imidazolate frameworks (ZIFs), carbon nanotubes (CNTs), porous organic cage molecules, and silicalite-1[202][203][204][205][206][207]. Mixed matric membranes are usually prepared to improve their gas permeation or separation properties of polymeric membranes.…”

“…20 In addition, they have excellent solvent-resistance, are only dissolved in chloroform, dichloromethane, and tetrahydrofuran, and show good stability in the aqueous organic solution. 16,[21][22][23] For these, the PIMs membranes should have a great potential in the pervaporation removal of VOCs from aqueous solutions. Very recently, the PIM-1 membranes are reported in the pervaporation removal of phenol and alcohols from water, showing a good permeability and moderate selectivity.…”

“…Very recently, the PIM-1 membranes are reported in the pervaporation removal of phenol and alcohols from water, showing a good permeability and moderate selectivity. [21][22][23] For example, a high flux of 8.0-26.8 kg lm m 22 h 21 and a separation factor of 16-18 are observed in the pervaporation of 1-5 wt% phenol aqueous solution. However, their applications are not exploited thoroughly and utilized efficiently in the pervaporation removal of VOCs, especially common organic solvents.…”

in Wiley Online Library (wileyonlinelibrary.com) Wastewater containing volatile organic compounds (VOCs) is generated in various industrial processes and is seriously harmful to the natural environment and human health. Its treatment has become extremely important due to increasing environment concerns. Here, a high permeable membrane for fast and high-efficient VOCs removal from aqueous solutions by pervaporation is reported. The as-prepared PIM-1 membrane allows ultrafast permeation of VOCs and exhibits excellent VOCs selectivity, particularly for ethyl acetate, dimethyl ether, and acetonitrile. Typically, the PIM-1 membrane exhibits an ultrahigh flux and separation factor of 39.5 kg lm m 22 h 21 and 189, respectively, in the pervaporation of 1.0 mol% aqueous ethyl acetate solution. Furthermore, the solubility-diffusion mechanism is revealed in the pervaporation of 10 kinds of 1.0 mol% VOCs solutions. It is found that the pervaporation performance is affected directly by physicochemical properties of VOCs. Moreover, effects of feed composition and temperature on the pervaporation are studied in details.

“…Besides these issues, the pores of MOF fillers can be blocked by polymer chains, when mixed together, which hinders the direct contact of gas molecules with the internal void space of the MOF particles [8,9]. In the last few years, various MMMs have been reported, based on PIM-1 and different inorganic [10], carbonaceous [11,12], organic [3] or MOF fillers [13,14,15] or a MOF/ionic liquid combination [16], with different effects on the gas permeability and selectivity.…”

Synthesis and Transport Properties of Novel MOF/PIM-1/MOF Sandwich Membranes for Gas Separation

et al. 2017

Metal-organic frameworks (MOFs) were supported on polymer membrane substrates for the fabrication of composite polymer membranes based on unmodified and modified polymer of intrinsic microporosity (PIM-1). Layers of two different MOFs, zeolitic imidazolate framework-8 (ZIF-8) and Copper benzene tricarboxylate ((HKUST-1), were grown onto neat PIM-1, amide surface-modified PIM-1 and hexamethylenediamine (HMDA) -modified PIM-1. The surface-grown crystalline MOFs were characterized by a combination of several techniques, including powder X-ray diffraction, infrared spectroscopy and scanning electron microscopy to investigate the film morphology on the neat and modified PIM-1 membranes. The pure gas permeabilities of He, H2, O2, N2, CH4, CO2 were studied to understand the effect of the surface modification on the basic transport properties and evaluate the potential use of these membranes for industrially relevant gas separations. The pure gas transport was discussed in terms of permeability and selectivity, highlighting the effect of the MOF growth on the diffusion coefficients of the gas in the new composite polymer membranes. The results confirm that the growth of MOFs on polymer membranes can enhance the selectivity of the appropriately functionalized PIM-1, without a dramatic decrease of the permeability.
