摘要: The invention provides asymmetric membranes composed of a microporous substrate whose pores contain a crosslinked gel, the density of the crosslinked gel being greater at or adjacent to one major surface of the membrane than the density at the other major surface. The membranes are useful for separating matter from liquids and display good flux and good rejection at low pressure.

摘要: Versions of the invention include electron beam treated microporous halocarbon membranes, particularly fluoro-carbon membranes, and methods for treating one or more surfaces of a polymeric porous halocarbon membrane with electron beams. The modified porous membrane is stable, resists dewetting, and retains its mechanical properties and chemical inertness.
