%X Protective clothing systems composed ofpermselective polymer film laminates are analternative to standard air-permeable garments basedon activated carbon. These polymer layers aredesigned with high water vapor permeation rates andlow permeation of chemical warfare agents. Polymerfilms that have a significant water vapor flux usuallyalso have an affinity for water, and will hydrate andswell significantly at high humidity levels. Thepolymer filmĄ¯s increase in water content has thepotential to affect the transport rate of chemicalwarfare agents in vapor and liquid form, and usuallyalso has a large effect on the intrinsic water vaporpermeability of the membrane.
