“…In this approach, nano-particulate fillers are added into the polymer phase, generally causing an enhancement in permeability and/or change in penetrant selectivity. A large number of MMMs using zeolites [4], silicas [5][6][7], carbons [8][9][10], metal-organic frameworks (MOFs) [11], zeolitic imidazolate frameworks (ZIFs) [12][13][14] and porous organic polymers (POPs) [15] have been shown to be promising candidates for gas separation applications. However, these MMMs are normally tested in isolation and rarely compared to each other.…”

Enhancing gas permeability in mixed matrix Membranes through Tuning the nanoparticle properties, Journal of Membrane Science, http: //dx. AbstractMixed matrix membranes containing a variety of nanoparticles were fabricated by the solvent casting method using a commercial aromatic polyimide as the base polymer. All gas permeabilities increased with increasing particle loading with no reduction in the selectivity, reflecting adequate polymer/particle compatibility. Importantly, under such conditions the permeability enhancement depended only upon the pore volume within the particle, regardless of the particle chemistry or the morphology of the membrane structure. Remarkably, despite a range of membrane chemistries and filler loadings, this permeability enhancement could be readily described with a simple free volume relationship. The results suggest that nanoparticle porosity should be the focus of research into mixed matrix membrane structures.These results are likely to apply in all diffusivity dominated systems where the particle pore size is significantly larger than the penetrant size, as is the case with glassy polymers and many inorganic additives at low pressures.

“…MMMs have become attractive for gas separation applications in recent years not only because of their enhanced thermal, chemical, and mechanical stability, but also their improved gas permeation/separation properties, when compared to homogeneous polymer membranes. To data, a large number of MMMs using carbon [17][18][19][20][21], zeolite [22][23][24][25], silica [26][27][28][29][30], metal organic frameworks (MOF) [31][32][33] and porous organic polymers (POP) [34] have been shown to be promising candidates for gas separation applications. Carbon materials are likely to be available at more moderate cost than other additives such as MOFs [35,36].…”

a b s t r a c tA series of mixed matrix membranes (MMMs) using nanoparticles involving carbons, porous organic polymers and metal organic frameworks (MOFs) were prepared to investigate the impact of water vapor on CO 2 separation performance. The water uptake of MMMs using hydrophilic MOFs increased relative to more hydrophobic particles such as the porous organic polymers and carbons and this trend was reflected in the water vapor permeability, which varied by a factor of three between the hydrophobic and hydrophilic MMMs. These changes in water vapor permeability were strongly correlated with the water solubility, indicating that it is this solubility that is the controlling parameter. The calculated water diffusivity was consistent with previously published results. The gas permeability of MMMs in the presence of water vapor was also strongly affected by the nanoparticle hydrophobicity, with membranes composed of hydrophobic fillers out-performing hydrophilic fillers of comparable porosity. However in general, the differences in performance between MMMs and the pure polymer narrowed in the presence of water vapor.

“…To date, because of low cost of polymeric materials, some researchers use polymeric materials whether as a pure membrane or as mixed matrix membranes, to prepare and examine them in order to purify hydrogen such as, PDMS/zeolite 4A [16][17][18], ZIF-8/6FDA-durene diamine [19], matrimid/zeolite 4A [20], PEO/silica [4], PBI/ZIF-8 [21], Poly(allylamine hydrochloride) crosslinked with poly(vinyl alcohol) [22], polyether-diamine [3], modified…”
