Annelides V: A New Type of Lyotropic Mesomorphic PHASE.

Abstract

Abstract The Annelides represent a new class of surfactants able to selectively complex a predetermined metallic ion. They are shown to form a novel type of lyotropic phase. This phase is thoroughly characterized by polarizing microscopy and X-rays determinations. It is found to be lamellar with a transition at 32°C to an isotropic phase. The main geometrical parameters are determined, in particular, the surface available for each polar head is calculated.
