Observation of Lyotropic Liquid Crystalline Phases in Some Transition Metal Salt Dispersed Soft Non‐Aqueous Systems

摘要

Present studies demonstrate the nucleation and stabilization of soft lyotropic liquid crystalline (LLC) phases, derived via transition metal salt (ZnCl_2? = ?1,3,5,10?wt?%) dispersion in a binary mixture (40:60 wt %) of cationic surfactant (cetyl pyridinium chloride) and protic polar solvent (ethylene glycol). Textural and structural investigations reveal the formation of mixed (hexagonal and lamellar) LLC phase at 1, 3, 5 wt % ZnCl_2 concentration, although, system show neat lamellar phase at higher metal salt content (10 wt %). Our textural and structural investigations were found in agreement with each other and hint at the origin, stability and diversity of these complex materials.
