摘要： A composite membrane for selectively separating (e.g., pervaporating) a first fluid (e.g., first liquid such as a high octane compound) from a mixture comprising the first fluid (e.g., first liquid such as a high octane compound) and a second fluid (e.g., second liquid such as gasoline). The composite membrane includes a porous substrate comprising opposite first and second major surfaces, and a plurality of pores. A pore-filling polymer is disposed in at least some of the pores so as to form a layer having a thickness within the porous substrate. The composite membrane further includes at least one of: (a) an ionic liquid mixed with the pore-filling polymer; or (b) an amorphous fluorochemical film disposed on the composite membrane.

摘要： Disclosed is a hollow fiber membrane module including a case and a hollow fiber membrane built in the case, wherein the hollow fiber membrane contains a polysulfone-based polymer and a hydrophilic polymer, and satisfies the following (A) and (B), and an amount of an eluted substance contained in a liquid obtained by circulating ultrapure water heated at 37°C through a passage of an inner surface side of the hollow fiber membrane for 4 hours at 200 mL/min is 1.0 mg/m 2 or less: (A) an insoluble component accounts for less than 3% by mass of the total mass of the hollow fiber membrane when the hollow fiber membrane is dissolved in N,N-dimethylacetamide; and (B) a flexible layer exists on a surface of a functional layer in a wet state and the flexible layer has a thickness of 7 nm or more. The present invention provides a hollow fiber membrane module including a hollow fiber membrane containing a polysulfone-based polymer and a hydrophilic polymer built therein, which elutes little eluted substance and exhibits high biocompatibility, while change in performance due to crosslinking of the hydrophilic polymer is suppressed.

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： The present invention generally related to a nanofabricated membrane including polymerized proteoliposomes. The nanofabricated membrane is a bio-nano fused selective membrane using protein-incorporated uv-crosslinkable liposomes with a chemical reactive biocompatible interstitial matrix. In the present invention, internally UV-crosslinked protein-incorporated proteolipsomes are used because the proteoliposomes made by natural lipids have a short life time and a weak resistance to the circumstantial stresses such as a high and low temperature, pressure, ionic strength etc. Furthermore, the proteo-vesicles made by amphiphilic block copolymers provide less consistency in accomplishing proper functionality batch to batch because of the inevitable polydiversity of the polymer.
