Abstract
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 × 10-9 gm mol/cm 2 min cm Hg and 37%, respectively.
