ABSTRACT A Landau model is proposed to describe the uniaxial – biaxial lyotropic cholesteric phase transition of lyotropic liquid crystals (LLC). The model free energy is based on a mixture of rod-shaped and disc-shaped micelles. The possibility of the existence of two biaxial lyotropic cholesteric phases and two uniaxial lyotropic cholesteric phases of LLC is discussed. The phase transitions between two biaxial lyotropic cholesteric phases and two uniaxial lyotropic cholesteric phases are explored. Qualitative comparisons between theoretical predictions and recent experimental results are discussed.
期刊介绍:
Providing a common forum for all soft matter scientists, Soft Materials covers theory, simulation, and experimental research in this rapidly expanding and interdisciplinary field. As soft materials are often at the heart of modern technologies, soft matter science has implications and applications in many areas ranging from biology to engineering.
Unlike many journals which focus primarily on individual classes of materials or particular applications, Soft Materials draw on all physical, chemical, materials science, and biological aspects of soft matter. Featured topics include polymers, biomacromolecules, colloids, membranes, Langmuir-Blodgett films, liquid crystals, granular matter, soft interfaces, complex fluids, surfactants, gels, nanomaterials, self-organization, supramolecular science, molecular recognition, soft glasses, amphiphiles, foams, and active matter.
Truly international in scope, Soft Materials contains original research, invited reviews, in-depth technical tutorials, and book reviews.
