Abstract

The mesomorphic, morphologic and optical refracting properties of the bicomponent amphiphilic lyotropic systems have been investigated. Five amphiphiles with various concentration combinations as cationic – cationic, anionic – anionic and cationic – anionic lyotropic mixtures have been used for preparation of lyotropic systems. The mixtures were prepared with a constant (amphiphile1 + amphiphile2)/water concentration ratio. Isotropic lyotropic phase and hexagonal and lamellar lyotropic mesophases have been found in lyotropic systems under investigations. Dynamics of change of the magneto-morphologic properties vs. time, character of the heterophase regions of the mesophase – isotropic liquid phase transitions and temperature dependencies of the optical refracting properties of these bicomponent amphiphilic lyotropic systems have been investigated.

Kurzfassung

Die mesomorphen, morphologischen und optischen Refraktionseigenschaften amphiphiler lipotroper Bikomponentensysteme wurden untersucht. Zur Herstellung der lyotropen Systeme wurden fünf Amphiphile in verschiedenen Konzentrationen zu kationisch-kationische, anionisch-anionische und kationisch-anionische lyotrope Mischungen kombiniert. Die Mischungen wurden mit einem konstanten Konzentrationsverhältnis von (Amphiphil1 + Amphiphil2) und Wasser hergestellt. In den lyotropen Systemen wurden die lyotrope-isotrope Phase, sowie hexotrope und lamellare Mesophasen gefunden. Die Änderungsdynamik der magnetomorphologischen Eigenschaften als Funktion der Zeit, die Eigenschaften der Heterophasenbereiche der mesophasenisotropen Flüssigphasenübergänge und die Temperaturabhängigkeit der optischen Brechungseigenschaften der amphiphilen lyotropen Bikomponentensysteme wurden untersucht.
