摘要 ：
Building up selective mass transfer channels in polymeric membranes is a promising strategy to fabricate effective separation membranes. Herein, a thioether-functionalized hydrazone-linked covalent organic framework, COF-LZU8, pre-modified by Ag ion, was incorporated for constructing aromatic selective channels within a commercial poly (ether-block amide) (Pebax 2533) membrane. The inside nanochannels of resulting membrane were effectively confirmed by measuring the affinity and the selective free volume to toluene via quartz crystal microbalance and low-field nuclear magnetic resonance. Owing to the selective channels, the Ag-COF-LZU8/Pebax membrane presented a considerably enhanced performance for toluene/n-heptane separation comparing with pristine Pebax membranes. The optimized membrane could perform a permeation flux of 293 g/m(2)h and a separation factor of 4.03 for the separation of 50 wt% toluene/n-heptane mixture.

摘要 ：
Recovery of butanol is a potential biofuel production process, which can be achieved through membrane separation technology. In this study, Zeolitic Imidazolate Framework-8 (ZIF-8) modified graphene oxide (ZGO) with polyether block amide (PEBA) was deposited on ceramic tubular substrate to prepare composite membrane for bio-butanol recovery. ZGO laminates can be used to form transport channels for butanol molecules to enhance the permeance. The affinity of laminate to butanol was improved because of the hydrophobic ZIF-8 particles. Therefore, the separation performance of ZGO/PEBA membrane was enhanced. The microstructure and chemical property of the ZGO/PEBA membranes were characterized. Different preparation and operation conditions were also investigated to optimize the separation performance. Moreover, ZGO/PEBA composite membranes were evaluated in model acetone-butanol-ethanol (ABE) solution, which also exhibited high butanol recovery performance. Therefore, this facile strategy may provide a potential application in the commercialized ABE fermentation process.

摘要 ：
A defect-free, robust and selective barrier is essential for manufacturing membranes with targeted high permeability and selectivity. Here we report a new route to engineering a separation composite membrane by confining both channels in nanoscale metal organic frameworks (MOFs) and charges in a polyelectrolyte in the inner space of a porous supportviaa counter-diffusion method. A simple thermal annealing treatment of the interface between the MOF, polymer and support favorably reduced voids inside this nano-confinement environment. As this composite membrane combines both the support and barrier as one, it minimizes mass transfer resistance of water molecules. In a separation test, it readily achieved the state-of-the-art permeance. This simple chemical approach to upgrade membrane structures will offer wide opportunities in separation devices.

摘要 ：
Organic solvent nanofiltration (OSN) is an emerging membrane-based technology for molecular separation. The design and fabrication of membranes with unique structures are important to obtain high performance. Herein, ZIF-8 nanoparticles are grown in situ on the surface of graphene oxide (GO) nanosheets and then assembled on a tubular ceramic substrate through a vacuum-assisted assembly method. ZIF-8 anchored on the GO nanosheets is evolved into ZnS polyhedra with a hollow structure through in situ sulfurization. The formed ZnS@GO membrane is composed of a layered structure of GO with the interlayer intercalated by ZnS hollow polyhedra and demonstrates high permeance for organic solvents. Compared to that of the ZIF-8@GO membrane, the permeance of the ZnS@GO membrane is enhanced by 4.4-fold when separating dyes from methanol, indicating their promising potential in the application of organic solvent nanofiltration.

摘要 ：
Organic solvent nanofiltration (OSN) is emerging as an efficient and emerging approach for separation and purification of solute from organic solvents, which however were severely underdeveloped because of the low permeance of membranes. Herein, a novel mixed matrix membrane (MMM) was developed by incorporation of modified mesoporous silica nanoparticle (MSN) into commercially-available polydimethylsiloxane (PDMS) matrix for removal of trace impurities, such as Evans blue or vitamin B12, from different organic solvents. Notably, because of the designed nanoscale spaces originated from MSN, the permeance of the optimized MMM reached up to 31.2 L m(-2).h(-1).MPa-1, around 17-fold enhancement compared with that of pristine PDMS membrane. Low-field nuclear magnetic resonance was employed to trace the solvent state in the MMM. The MMM exhibited high MeOH absorption capability but low-swelling attribute, certificating the high permeance and long-term stability of the MMM. The MMM was stably tested in MeOH solution for more than 80 h, indicating the great promise for future practical OSN applications.

摘要 ：
NaA membranes are recognized as one of the most promising materials for fabrication of high-performance pervaporation membrane for dehydration, which has been widely employed in dehydration industry. However, the chemical structure breakage of NaA in acidic conditions severely hampered the application of NaA membrane in purification of biomass fermentation. In order to overcome this bottleneck, we proposed construction of a protective acid-resistant skin on the 3D surface of NaA tube. The protective layer was prepared by self-assembly of sodium alginate (SA) and CaCl2, which formed the 'egg-box' network via crosslinking SA with Ca2+. The effect of cross-linking, SA concentration, layer numbers and operation pH on the membrane performance was investigated. When applied for pervaporation at acidic feed, the protective skin was partly broken, but it can be re-crosslinked again by simple ionic exchange to form a solid acid-resistant skin. After the re-crosslinking treatment, the performance of membrane can be recovered (the water content in the permeate and the flux were 99.6 wt% and 860 g/(m(2)h), respectively) with operation condition at pH = 2. Notably, the membrane can be continuously operated in acid feed for 100 h and showed no obvious performance degradation.

摘要 ：
In order to develop high performance composite membranes for alcohol permselective pervaporation (PV), poly (dimethylsiloxane)/ZIF-8 (PDMS/ZIF-8) coated polymeric hollow fiber membranes were studied in this research. First, PDMS was used for the active layer, and Torlon (R), PVDF, Ultem (R), and Matrimid (R) with different porosity were used as support layer for fabrication of hollow fiber composite membranes. The performance of the membranes varied with different hollow fiber substrates was investigated. Pure gas permeance of the hollow fiber was tested to investigate the pore size of all fibers. The effect of support layer on the mass transfer in hydrophobic PV composite membrane was investigated. The results show that proper porosity and pore diameter of the support are demanded to minimize the Knudsen effect. Based on the result, ZIP-8 was introduced to prepare more selective separation layer, in order to improve the PV performance. The PDMS/ZIF-8/Torlon (R) membrane had a separation factor of 8.9 and a total flux of 847 g.m(-2).h(-1). This hollow fiber PDMS/ZIF-8/Torlon (R) composite membrane has a great potential in the industrial application.
