Patent number: 10888824Abstract: 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 at least one surface of the membrane with a treatment composition of a silane-functional polyamine compound having at least one alkoxy silane group, such that the silane-functional polyamine compound is in intimate contact with the filler present in the matrix; and (2) subjecting the membrane of (1) to conditions sufficient to effect a condensation reaction between the inorganic filler and the silane-functional polyamine compound. Treated membranes also are provided.Type: GrantFiled: November 16, 2016Date of Patent: January 12, 2021Assignee: PPG Industries Ohio, Inc.Inventors: Qunhui Guo, James C. Peters, Luciano M. Parrinello, Linda K. Anderson
