Liquid crystals (LCs)/polymer composites are promising candidates for the next-generation of large-area processible and flexible electro-optical (E-O) materials due to their combination of the fast-responsive characteristics of LCs and the excellent physical properties of polymer. However, the current LCs/polymer system, represented by the polymer dispersed liquid crystals (PDLC), are suffering from limitations of their normally opaque optical states, because the porous polymer matrix in PDLCs are lack of orientation control over LCs. Herein we promote a new category of LCs/polymer composite film from a polymeric system containing dual-frequency liquid crystals, liquid-crystalline polymerizable monomers and isotropic polymerizable monomers. By creating a polymer-stabilized-liquid-crystal like polymer microstructure within a PDLC like porous matrix, the promoted composite film features programmable electro-optical performances, excellent flexibility and enhanced robustness. Most importantly, the normal optical states can be regulated from opaque to transparent through microstructure control, showing great potential E-O applications in practical uses.

液晶（LC）/聚合物复合材料由于具有LC的快速响应特性和聚合物出色的物理性能的组合，因此是下一代大面积可加工和柔性电光（EO）材料的有希望的候选者。但是，目前的以聚合物分散液晶（PDLC）为代表的LC /聚合物系统正受到其通常不透明光学状态的限制，因为PDLC中的多孔聚合物基质缺乏对LC的取向控制。本文中，我们从包含双频液晶，液晶可聚合单体和各向同性可聚合单体的聚合物系统中推广了新型的LCs /聚合物复合膜。通过在类似于多孔基质的PDLC中创建类似于聚合物稳定液晶的聚合物微结构，推广的复合膜具有可编程的电光性能，出色的柔韧性和增强的坚固性。最重要的是，可以通过微结构控制将正常的光学状态从不透明调节为透明，从而在实际应用中显示出巨大的潜在EO应用。
