title: Unexpected barrier properties of structurally matched and unmatched polyelectrolyte multilayers.
abstract: Structurally unmatched hyperthin (14 nm) polyelectrolyte multi-layers (PEMs) formed on poly[1-(trimethylsilyl)-1-propyne] supports exhibit exceptionally high CO(2)/N(2) permeation selectivities, ranging from 100 to 150. Structurally matched PEMs show similar selectivities with significantly higher permeances.
