用显微镜研究了液晶-单体混合物中边缘场诱导的相分离动力学。在低LC浓度下，边缘场将随机分散的LC液滴转化为有序的液滴阵列，而在高LC浓度下，边缘场将无定形LC-单体系统转化为复合膜。因为LC和单体是不混溶的，所以即使在去除电压之后，转化的形态也是稳定的。利用边缘场诱导的相分离，可以制备不同形态的聚合物分散液晶。
Fringing-field-induced phase separation dynamics in liquid-crystal-(LC-)monomer mixtures is investigated via a microscope. At a low LC concentration, the fringing field converts the randomly dispersed LC droplets to an ordered droplet array, while at a high LC concentration the fringing field converts the amorphous LC-monomer system to a composite film. Because the LC and monomer are immiscible, the converted morphologies are stable even after the voltage is removed. Using the fringing field-induced phase separation, it is possible to prepare different polymer-dispersed LC morphologies.
