Metal‐Organic Frameworks: Visualizing MOF Mixed Matrix Membranes at the Nanoscale: Towards Structure‐Performance Relationships in CO₂/CH₄ Separation Over NH₂‐MIL‐53(Al)@PI (Adv. Funct. Mater. 2/2014)

Fabrication of MMMs with improved gas separation properties using externally-functionalized MOF particles

“…More sophisticated techniques like nano-computed tomography scanning (nano-CT), positron annihilation lifetime spectroscopy (PALS), or FIB-SEM are needed to detect if there are any nano-defects or rigidication of the polymer around the particle. 30,31,50 Fig. 5 shows the Young's Modulus of the pure Matrimid ® and MMMs as determined by dynamic mechanical analysis (DMA).…”

“…[20][21][22][23][24] As a result of their organic/inorganic hybrid structure, MOFs are intrinsically more compatible with polymers and show greater promise as ller materials in MMMs compared to other inorganic materials. 6,10,14,[25][26][27][28][29][30][31] Several different MOFs were used to fabricate MMMs such as Cu 3 BTC 2 , 25 ZIF-8, 28 MOF-5 29 and MIL-53. 30 HKUST-1 and ZIF-8 were also used in combination with silicalite-1 zeolites to prepare MMMs by dispersing in polysulfone polymer.…”

High performance mixed matrix membranes (MMMs) composed of ZIF-94 filler and 6FDA-DAM polymer

“…Moreover, in contrast with zeolites, due to their partially organic nature, MOFs usually display better polymer-filler compatibility. This prevents formation of non-selective voids at the polymerfiller interface and consequently defect free membranes can be made [18]. One of the first reports of a MOF used in a MMM concerned the additions of copper biphenyl dicarboxylate-triethylene diamine to poly (3-acetoxyethylthiophene (PAET) [19].…”

An overview: synthesis of thin films/membranes of metal organic frameworks and its gas separation performances

“…In the past two decades, the synthesis of metal organic frameworks (MOFs) has attracted tremendous attention due to its plausible potential to obtain exceptionally interesting structures for applications in various elds related to porous materials, including carbon capture and storage, 1-5 separation applications, [6][7][8][9][10][11] and catalysis, [12][13][14][15][16][17] depending on the pore size and shape as well as the host-guest interactions involved. 18 Several excellent reviews published on MOFs could be found in the literature.…”
