In this paper we report for the first time the development of poly(acrylamide-co-acrylic acid) (PAMAC) hydrophilized porous polypropylene composite membrane for dehumidification applications. The sorption of water vapor on PAMAC functional groups was found to be quite high, and reached nearly a gram per gram of the membrane. This allowed high water vapor permeance and percent water removal that reached 2 x 10(-9) gm mol/cm(2) min cm Hg and 37%, respectively. (C) 2013 Elsevier B.V. All rights reserved.
