Abstract
A functionalized microporous, mesoporous, or nanoporous membrane, material, textile, composite, laminate, or the like, and/or a method of making or using such functionalized membranes. The functionalized porous membrane may be a functionalized microporous, mesoporous, or nanoporous membrane that has a functional molecule attached, such as a functional polymer, to the surface and/or internal fibrillar structure of the membrane.
Claims22
A composite comprising:
- a microporous, nanoporous, or mesoporous membrane and an oleophobic coating or treatment on at least one side of the membrane, wherein the composite has a JIS Gurley of 200 seconds or less, and wherein the JIS Gurley of the composite is about the same as the JIS Gurley of the membrane without any coating or treatment.
A functionalized porous membrane comprising a microporous, nanoporous, or mesoporous membrane and a functionalizing coating or treatment on at least one side of the membrane, wherein the functionalized porous membrane has a JIS Gurley of 200 seconds or less, and wherein the JIS Gurley of the composite is about the same as the JIS Gurley of the membrane without any coating or treatment.
A textile, film, laminate, fiber, hollow fiber, filtration material, separations material, or a combination thereof, comprising a microporous, nanoporous, or mesoporous membrane and a functionalizing coating or treatment on at least one side of the membrane, wherein the functionalized porous membrane has a JIS Gurley of 200 seconds or less, and wherein the JIS Gurley of the composite is about the same as the JIS Gurley of the membrane without any coating or treatment.
