Title: Unusual pressure effects on the permeation properties of a Langmuir-Blodgett composite membrane

Abstract

In this paper, the authors document their discovery of extraordinary permeation properties of composite membranes derived from Langmuir-Blodgett (LB) multilayers of calix[6]arene I plus poly[1-(trimethylsilyl)-1-propyne] (PTMSP) film. Specifically, it is shown that the intrinsic permeability and selectivity of such composites toward He and N{sub 2} increase with increasing permeant pressures. In striking contrast, analogous composites prepared with a `conventional` polymeric surfactant, poly(1-octadecene-co-maleic anhydride) (II) show unexceptional behavior, i.e., permeation characteristics that are independent of pressure. The theoretical and practical implications of these findings are briefly discussed. 8 refs., 2 figs.
