Shear stress temperature dependences of nematic-cholesteric mixtures

Abstract

The actuality of liquid crystal (LC) materials with supermolecular helix structure studies is caused by their wide using for information display and processing devices, such as large information boards, portable reflective displays etc. The main studies directions are synthesis of new compounds, surface stabilization development, design of new concepts of electronic driving circuits. For a wider use of these materials use it is necessary to solve the problem of complex influence of dielectric anisotropy, supermolecular helix pitch, elastic constants and viscosity on electro-optic effects and phase transitions in these materials. The multicomponent mixtures studies are the most interest and perspective.
