Abstract: The present invention is a method for modifying at least one property of a porous membrane. The method comprises the steps of providing a porous membrane. The method also includes exposing the membrane to a fluid at supercritical conditions. At least one property of the membrane is modified while the membrane is exposed to the fluid at supercritical conditions. The condition of the fluid is changed in such a manner that the porous membrane retains the modified property. The present invention is also sheet material that is water-resistant, moisture vapor transmissive and air permeable. The sheet material comprises a membrane having an open pore structure including surfaces defining a plurality of interconnecting pores extending through the membrane and between major sides of said membrane in which the pores have an average pore size. The membrane is made from a material tending to absorb oils and contaminating agents. A uniform coating of precipitated fluorinated urethane polymer material on at least portions of the surfaces of the nodes and fibrils defining the pores. The precipitated fluorinated urethane polymer material provides oil and contaminating agent resistance of at least a number 6 by AATCC 118 testing and an air permeability of at least 0.20 CFM per square foot by ASTM D737 testing.

Abstract: A method of making a composite membrane with ion exchange properties includes, in an exemplary embodiment, forming a porous membrane from a first material, dissolving a coating material in a fluid at supercritical conditions, and exposing the porous membrane to the coating material dissolved in the supercritical fluid. The method also includes precipitating a uniform coating of the coating material onto an exterior surface of the porous membrane by changing the supercritical conditions of the fluid to a non-supercritical condition, and applying an ion exchange material to the coated porous membrane so that the ion exchange material is in intimate contact with substantially all of the coated surfaces of the porous membrane.
