A laminated thin-film composite (TFC) membrane system consisting of an ultrafiltration support; an ordered, nanoporous, polymerized lyotropic liquid crystal (LLC) intermediate layer; and an ultra-thin, dense polydopamine top layer was developed for use as a “breathable” chemical-protective garment material. These membranes exhibit a high water vapor transport rate (ca. 500 g m –2 day –1 ) and excellent rejection of both CEES (a blister agent simulant) and DMMP (a nerve agent simulant) vapors under ambient conditions. The (water:CEES) and (water:DMMP) molar vapor selectivity values of this new composite membrane system were found to be 170 ± 40 and &gt;3400 , respectively, which exceed those of any previously reported LLC-based membrane system.<br/>
