Patent number: 6734386Abstract: A microporous PVDF membrane is rendered hydrophilic without making it brittle or lowering its heat resistance by exposing the membrane to a plasma under controlled conditions. Specifically, a microporous PVDF membrane is first coated with an appropriate monomer. After the monomer dries, the membrane is exposed to the plasma. Any remaining uncured monomer on the membrane is removed. Thereafter, the membrane is pleated and incorporated in a filter cartridge.Type: GrantFiled: February 5, 2002Date of Patent: May 11, 2004Assignee: Meissner Filtration Products, Inc.Inventors: Siegfried Lauterbach, Christopher A.
