A Smectic-A Type Lamellar Amphiphilic Lyotropic Liquid Crystal Phase

Abstract

Preliminary polar micrographic studies suggest in the binary cesium perfluoro-octanoate/heavy water system more than one smectic type phase exists in the lamellar region. The lamellar phase on the low water side of the nematic was examined and from the micrographic textures it is suggested the structure of the phase is related to the classical thermotropic smectic-A S_A mesophase.
