蓝相液晶由于其出色的电光性质在信息显示和光电子领域受到了广泛的关注,然而日益发展的信息技术对信息的传递、处理、存储速度提出了更高的要求。为了进一步强化蓝相液晶的快速电光响应优势,本文以双频向列相液晶为主体,掺杂聚合单体、手性剂、光引发剂等材料制备了聚合物稳定双频蓝相液晶,通过调节双段电压脉冲时长,实现了聚合物稳定双频蓝相液晶的快速电光调控,其电光调控的开关时间均小于500 ns。
Blue phase liquid crystals have received widespread attention due to their excellent electro-optical properties for applications in information display and optoelectronic devices. Nowadays, the ultra-rapid development of information technology is posing even higher demands on the speeds of information delivery, processing and storage. To further improve the response time of blue phase liquid crystal in electro-optical performance, we utilize a dual-frequency nematic liquid crystal as the host, doped with reactive monomer, chiral dopant, photo-initiator to prepare polymer-stabilized dual-frequency blue phase liquid crystals (PS-DF-BPLCs). By adjusting the durations of the two voltage pulses, fast electro-optical response of PS-DF-BPLCs is achieved. Both the switching-on and switching-off processes of the PS-DF-BPLC are less than 500 ns.
