Zusammenfassung:Microporous membrane composites are disclosed. These microporous membrane composites are wet with solutions of methanol and water and are non-dewetting following autoclave treatment in water. The microporous membrane composites comprise a microporous membrane support, the microporous membrane support comprising a coating on pores and surfaces, and the coating comprises an armorphous ionomer including acid hydrophilic groups. The microporous membrane composites are non-dewetting following autoclave treatment in water. The microporous membrane composites are wet with solutions of methanol and water. Compared with the microporous membrane support, the microporous membrane composite has a flow loss on average in isopropyl alcohol of less than 82% when measured using 500 milliliters of isopropyl alcohol at a pressure of 97,905 Pa.
