The invention is a membrane comprising polymerized monomer and oligomer components. A primary membrane oligomer component is selected from acrylic polyester urethanes, and a secondary membrane monomer component is selected from 1,1,3,3-tetramethylbutylacrylamide and perfluoromonomers and perfluoroacrylic monomers. The membrane is further characterized as being microporous, permeable and having a thickness of less than 0.1 inches.
