摘要：
The present invention provides a supported microporous filtration membrane comprising a porous nonwoven fibrous support material having first and second sides, and a continuous microporous membrane having first and second zones, wherein the first side of the support material is integral with the first zone while not protruding into the second zone, and the first zone has a pore size at least about 50% greater than the pore size of the second zone. A method of preparing such a supported microporous membrane is also provided by the present invention.
