一种新的双轴向液晶相理论上预测在低分子量液晶分子和刚性棒状聚合物,如碳纳米管和液晶聚合物,其中两个组件有利于相互垂直的取向的混合物。我们表明,棒分散在液晶诱导的第二取向有序,并产生一个双轴取向相的温度-浓度平面上,取决于一个棒和液晶之间的各向异性相互作用。
A novel biaxial nematic phase is theoretically predicted in mixtures of a low-molecular-weight liquid crystalline molecule and a rigid rod-like polymer, such as carbon nanotubes and liquid crystalline polymers, where the two components favour a mutually perpendicular orientation. We demonstrate that rods dispersed in nematic liquid crystals induce the second orientational ordering and yield a biaxial nematic phase on the temperature–concentration plane, depending on an anisotropic interaction between a rod and a liquid crystal.
