  • Non-dewetting porous membranes
    Patent number: 10179842
    Abstract: Microporous membrane composites that are non-dewetting 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 that is coated with a crosslinked ionomer comprising hydrophilic groups. Compared to the microporous membrane support, the microporous membrane composite has a flow loss on average in isopropyl alcohol of less than 82%.
    Type: Grant
    Filed: January 29, 2016
    Date of Patent: January 15, 2019
    Assignee: Entegris, Inc.
    Inventors: Alketa Gjoka, Ven Anantha Raman, Matthias Gebert, Claudio Oldani, Alessandro Ghielmi
