制备了侧链型液晶聚合物（LCP）和化学结构与LCP侧链相类似的低分子量液晶（LMWLC）的二元混合物。在整个浓度范围内，LCP和LMWLC之间在中间相状态下获得了良好的相容性。随着LMWLC含量的增加，电场作用下分子重取向的响应时间显著缩短。提出了一种基于光散射的近晶态混合体系的新型可逆电光效应。
Binary mixtures composed of side chain type-liquid crystalline polymer (LCP) and low molecular weight liquid crystal (LMWLC) of which chemical structure is similar to the mesogenic side chain of LCP were prepared. Good miscibility between LCP and LMWLC was obtained in a mesophase state over a whole range of concentration. Response time of molecular reorientation by an imposed electric field remarkably decreased with an increase in the fraction of LMWLC. A new type of reversible and bistable electro-optical effect based on light scattering was proposed for the mixture system in a smectic state.
