将铁电液晶液滴封装在聚合物膜中提供了一种方便的方法来获得快速切换，灵活的电光光快门。聚合物分散的铁电液晶膜可以通过由于聚合诱导的相分离的光聚合形成。在此过程中，通过剪切流获得液晶的均匀取向。我们关于制备参数对电光性能影响的研究表明，在高聚合速率和低剪切速度下可以实现非线性电光行为。
The encapsulation of ferroelectric liquid crystal droplets in a polymer film provides a convenient method to get fast switching, flexible electro‐optic light shutters. The polymer‐dispersed ferroelectric liquid crystal films can be formed by photopolymerization due to a polymerization‐induced phase separation. A uniform orientation of the liquid crystal is obtained by shear flow during this process. Our studies concerning the influence of the preparation parameters on the electro‐optic properties show that a bistable electro‐optic behavior can be achieved for high polymerization rates and low shear velocities.
