Patent number: 11618016Abstract: A polysulfone membrane is modified so that monomers are wafted onto the surface of the membrane. The polysulfone membranes can be grafted by contacting the membrane with a grafting solution and exposing the membrane to electromagnetic radiation, typically within the ultraviolet portion of the spectrum. The monomers that are grafted are typically anionic or cationic. The grafted membranes can be used for filtering impurities, such as positively and negatively charged particles, from a liquid. Anionic membranes provide improved filtration of negatively charged impurities, while cationic membranes provide improved filtration of positively charged impurities.Type: GrantFiled: October 18, 2021Date of Patent: April 4, 2023Assignee: ENTEGRIS, INC.Inventors: Jad Ali Jaber, Alketa Gjoka, Saksatha Ly
