In this paper, two types of polymer-stabilized blue-phase liquid crystals (PS-BPLCs) with different monomers were designed and prepared. The morphology, temperature range and electro-optical properties of the blue phases were studied and discussed. The temperature range of both types of PS-BPLC is greater than 110 °C, and both samples can be stabilized well at room temperature. The organosilicone monomer 3-methacryloxypropyltrimethoxysilane (KH570), which contains double bonds, was introduced to a blue-phase system for the first time. Regarding the electro-optical performance, the on-state voltage of the PS-BPLCs with the KH570 monomer is reduced to 30 V compared with traditional C12A monomer systems in which the on-state voltage is 75 V at 458 nm. Meanwhile, a fast response and suppressed hysteresis are obtained. These results are helpful to the application of displays and photonic devices.
本文设计并制备了两种含不同单体的聚合物稳定蓝相液晶（PS - BPLCs）。研究并讨论了蓝相的形态、温度范围和电光特性。两种类型的PS - BPLC的温度范围均大于110℃，且两个样品在室温下都能很好地稳定。首次将含双键的有机硅单体3 - 甲基丙烯酰氧基丙基三甲氧基硅烷（KH570）引入蓝相体系。在电光性能方面，含KH570单体的PS - BPLCs的导通电压在458nm处降至30V，而传统C12A单体体系在该波长下的导通电压为75V。同时，获得了快速响应和抑制的滞后现象。这些结果有助于显示器和光子器件的应用。
