高分子と液晶の混合系の理論

抄録

A simple model is introduced to describe liquid crystal transitions and macroscopic phase separations in binary mixtures of a flexible polymer and a liquid crystal. We examine binodal and spinodal lines on the temperature-concentration plane. We predict the appearance of new phase separations such as the smectic A-nematic, smectic A-isotropic, and smectic A-nematicisotropic phase separations. We also find a tricritical point caused by the interference between liquid crystal transitions and phase separations.
