Abstract

The occurrence of nematic and lamellr mesophases in concentrated surfactant / water mixtures is a well documented phenomenon. This work examines the structure and order of the mesophases exhibited by two sample systems, caesium pentadecafluorooctanoa-te (CsPFO) / heavy water, and decylammonium chloride / ammonium chloride / heavy water, and their dependence on temperature and composition. The results obtained are discussed with relatIon to inter- and intra-micellar interactions leading to the proposition of an attractive intermicellar interaction at high surfactant concentration.
