摘要： Stripped porous polymer film and a method for making such film from substantially heterogeneous porous polymer film are described. The heterogeneous film has surface characteristics that are different from the characteristics of the interior bulk material, and the method comprises mechanically stripping at least a portion of at least one surface layer from the heterogeneous film. The stripped porous polymer film may be incorporated into composite membranes. Such composite membranes are particularly suitable for incorporation into membrane electrode assemblies for use in electrochemical cells, including electrochemical fuel cells.

摘要： Presented is a method for preparing a gas separation membrane system. This method involves depositing a membrane layer of gas-selective metal upon a tubular porous support followed by annealing the resulting layer of gas-selective metal. The resulting annealed membrane layer of gas-selective material is polished under a controlled polishing condition with an abrading medium that includes a structured abrasive article comprising a backing having bonded thereto an abrasive layer comprising a plurality of shaped abrasive composites that comprise abrasive grains dispersed in a polymeric binder. Another layer of gas-selective metal is then deposited upon the tubular porous support. The cycle of annealing, polishing and depositing is repeated through one or more cycles until a leak-tight membrane system is provided.

摘要： The invention relates to a porous membrane having a particle filtration value of at least 10 under U.S. Military Standard MIL-STD-282 (1956), where the porous membrane is a polyethylene membrane made from a blend of UHMWPE and UMWPE. The membranes according to the invention are particularly useful for filters such as ASHRAE filters, HEPA filters and ULPA filters for example in heating, ventilating, respirators and air conditioning applications. The membranes are produced involving a biaxial streching step at low deformation speed.

摘要： A method for producing a hollow yarn wherein a mixture of a poly(vinylidene fluoride) and an organic liquid or a mixture of poly(vinylidene fluoride), an organic liquid and an inorganic fine powder is melt-kneaded and extruded, to form a hollow fiber, and then the organic liquid or the organic liquid and the inorganic fine powder are extracted from the hollow fiber, characterized in that the method further comprises drawing the hollow fiber before or after extraction and then allowing it to shrink. The method permits the production with stability of a hollow yarn film which has minute pores and exhibits high water permeability, and is excellent in durability and stain resistance, and thus can be suitably used for filtration such as the removal of turbidity.
