Lyotropic Nematics are liquid crystalline mixtures characterized by anisotropic aggregates of amphiphilic molecules with finite shape and long range orientational but no positional order. They are distinguished according to their macroscopic properties in positive and negative uniaxial nematics and in biaxial nematics. Very few notices are available on the structure and on the evolution of the micelles through the different nematic mesophases. We have studied by Small Angle Neutrons Scattering the potassium laurate, decylammonium hydrochloride, water system which was found to exhibit the three nematic phases as a function of temperature and concentration.

Abstract
Lyotropic Nematics are liquid crystalline mixtures characterized by anisotropic aggregates of amphiphilic molecules with finite shape and long range orientational but no positional order. They are distinguished according to their macroscopic properties in positive and negative uniaxial nematics and in biaxial nematics. Very few notices are available on the structure and on the evolution of the micelles through the different nematic mesophases. We have studied by Small Angle Neutrons Scattering the potassium laurate, decylammonium hydrochloride, water system which was found to exhibit the three nematic phases as a function of temperature and concentration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
