摘要： A polysulfone membrane is modified so that monomers are grafted 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.

摘要： The present invention is directed to a method for treating a surface of a filled microporous membrane. The microporous membrane includes a polyolefinic matrix, inorganic filler distributed throughout the matrix, and a network of interconnecting pores throughout the membrane. The method includes sequentially (1) contacting the membrane with a first treatment composition comprising an epoxy-silane which is in intimate contact with the inorganic filler; (2) subjecting the membrane of (1) to conditions sufficient to effect a first reaction between the inorganic filler and the silane groups of the epoxy-silane compound; (3) contacting the membrane of (2) with a second treatment composition comprising polyalkylene polyamine, an amine functional polysaccharide and/or an amino silane; and (4) subjecting the membrane of (3) to conditions sufficient to effect a second reaction. Treated membranes also are provided.
