摘要： Provided is a technique for fabricating a novel thin membrane with a starting material such as a biocompatible compound that is not easily processible into a membrane, particularly a technique for fabricating a novel thin membrane of a composition that is gradually polymerized from a membrane surface into the membrane in the cross sectional direction of the membrane, and having, for example, different structures on the front and back of the membrane. The technique includes the steps of preparing a solution of a starting material compound; forming a thin membrane of the solution on a base material surface; and forming the organic polymer thin membrane through a polymerization reaction caused by irradiating the exposed surface of the thin membrane with a plasma or an electron beam.

摘要： One aspect of the present invention relates to a method for modifying one side of a PTFE membrane by using HFCVD to deposit a PTFE film on one side of the PTFE membrane. The precursor fluorocarbon gas is preferably hexafluoropropylene oxide, which upon pyrolysis under HFCVD conditions forms reactive CF2 species. The present invention also relates to a modified PTFE membrane having a PTFE film on only one side, wherein the PTFE film has a porosity of greater than about 30% and a dangling bond density of less than about 1018 spins/cm3. The invention further provides a method of filtering a liquid or gas or a mixture of the two, comprising passing the liquid or gas or mixture of the two through the modified PTFE membrane of the present invention.

摘要： Porous polymeric materials are hardened by a process of plasma-annealing, involving treatment of at least one surface with a gas plasma formed by glow discharge through a gas containing a saturated alkane or an acetylene. Plasma-annealed porous polymers with reduced adsorption toward proteins were obtained by exposure to a glow discharge through a gas mixture containing an alkane such as methane in combination with oxygen, air, or a hydrophilic unsaturated organic monomer. For example, porous polysulfone sheet and hollow fiber were plasma-annealed by treatment with a gas plasma containing methane and air or acrylic acid with simultaneous deposition of a hydrophilic polymerizate thereon.

摘要： A device and method for selectively removing one or more components from a multicomponent gas/vapor mixture by membrane fractionation. The membrane fractionation gas removal system preferably comprises: a feed chamber which contains the gas/vapor mixture; at least one porous membrane having a first side which contacts the gas/vapor mixture in the feed chamber, and a second side; at least one nonporous membrane having a first side which contacts the second side of the at least one porous membrane, and a second side, the nonporous membrane having a permeability selective to one or more components; an exit chamber connected to the second side of the at least one nonporous membrane such that the component exiting the nonporous gas enters the exit chamber; and an evacuation member connected to the exit chamber for evacuating one or more components from within the exit chamber. The one or more components are transported through the porous membrane, adsorbed out of the gas/vapor multicomponent gas mixture onto the surface of the porous membrane, through the nonporous membrane, and into the exit chamber. The one or more components preferably condense within the pores of the at least one porous membrane.
