摘要：

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.
