摘要： Provided herein are metal organic framework/polymer mixed-matrix hollow fiber membranes and metal organic framework/carbon molecular sieve mixed-matrix hollow fiber membranes. The materials have high MOF particle loading and are easily scalable. The MOF/polymer mixed-matrix hollow fibers are formed using a dry-jet/wet-quench fiber spinning technique and show C3H6/C3H8 selectivity that is significantly enhanced over the pure polymer fiber and that is consistent with the selectivity of mixed-matrix dense films of the same MOF/polymer combination. The MOF/CMS mixed-matrix hollow fibers are formed by pyrolyzing the MOF/polymer mixed-matrix hollow fibers and show increased C3H6 permeance and increased selectivity over the MOF/polymer mixed-matrix hollow fiber membranes.

摘要： A porous membrane made from a poly(phenylene ether) copolymer has at least one of: a molecular weight cut off of less than 40 kilodaltons or a surface pore size of 0.001 to 0.1 micrometers. The porous membrane is made by dissolving the poly(phenylene ether) copolymer in a water-miscible polar aprotic solvent to form a porous membrane-forming composition; and phase-inverting the porous asymmetric membrane forming-composition in a first non-solvent composition to form the porous membrane. The porous membrane can be in the form of a sheet or a hollow fiber, and can be fabricated into separation modules.

摘要： A nozzle for making a reinforced hollow fibre membrane discharges one or more reinforcing yarns at or near a plane where the dope exits the nozzle, or in the same plane as a discharge opening of dope passage, or both. Multiple discrete yarn discharge openings may be spaced around a longitudinal axis of the nozzle. A reinforcing yarn passage remains generally free of dope during use. The dope may be discharged in an annular ring inside of the one or more reinforcing yarns, in an annular ring outside of the reinforcing yarns, or both. Minimal tension is required to pull the yarns through the nozzle, which helps to reduce distortion of the membrane cross section in a coagulation bath.

摘要： A composite hollow ceramic fiber includes a porous hollow core supporting a thin, dense sheath. The non-gas-tight core comprises a first ceramic material and an interconnecting network of pores. The gas-tight sheath comprises a second ceramic material. The fiber is made by extruding core and sheath suspensions from a spinnerette. The core suspension includes particles of the first ceramic material, a polymeric binder, a solvent, and a pore former material insoluble in the solvent. The sheath suspension includes particles of the second ceramic material, a polymeric binder and a solvent. The nascent hollow fiber is coagulated in a coagulant bath to effect phase inversion of the polymeric binders. The resultant green fiber is sintered in a two step process. First, the binders and pore former material are burned off. Second, the sheath is densified and the second ceramic material is sintered without fully sintering the core.

摘要： Permselective asymmetric membranes suitable e.g. for hemodialysis, hemodiafiltration and hemofiltration of blood, and having improved performance, including improved sieving characteristics, providing enhanced removal of middle molecular weight substances, e.g. inflammatory mediators having a molecular weight between 20 and 40 kDa. The improved sieving characteristics are due to a narrow pore size distribution of the membranes created in the production process. Processes for the preparation of these membranes, devices comprising these membranes, and the use of these membranes in hemodialysis, hemodiafiltration and hemofiltration of blood, as well as in bioprocessing, plasma fractionation and the preparation of protein solutions.
