Abstract:
A flexible liquid-water-resistant, water-vapor-permeable, composite comprised of:a). a layer of a microporous polymer film that is water-vapor-permeable, and a microporous structure comprising a microporous polymer that has a coating on at least a portion of the pore walls of the microporous polymer, of a second material that imparts greater oleophobicity to the microporous polymer, said layer of microporous polymer film having been treated to render it oleophobic so that it has an oil rating of at least 2; said layer adhered tob). an air-impermeable polymer that is water-vapor-permeable; andc). a layer adhered to the side of layer b) that is opposite layer a), said layer c) having a water-vapor-permeable microporous structure comprising a microporous polymer that has a coating on at least a portion of the pore walls of the microporous polymer, of a second material that imparts hydrophilicity to the microporous polymer.
