聚合物稳定蓝相液晶具有亚毫秒级响应速度
光学各向同性及无需配向工艺等特点
在显示及光子器件领域有广泛的应用。本文研究了一种基于聚合物稳定蓝相液晶的多重聚合物材料掺杂系统。聚合物稳定蓝相液晶的驱动电压可以通过掺杂N-乙烯吡咯烷酮(NVP)和聚苯胺氧化石墨烯(G-PANI)得到大幅度的降低。经过优化掺杂物的配比
多重掺杂的聚合物稳定蓝相液晶材料的科尔常数被提高了68%
并且不会对材料的响应时间、磁滞及残留双折射产生负面影响。
Polymer-stabilized blue phase liquid crystal (PSBPLC) shows great potential application in displays and photonic devices due to its properties of submillisecond response time
optical isotropic status
and alignment free.A multi-dopant material system for polymer-stabilized blue phase liquid crystal is proposed.The driving capacity of PS-BPLC can be improved by doping N-vinylpyrrollidone (NVP) and polyaniline functionalized graphene (G-PANI).With the dopant optimization
the Kerr constant of PS-BPLC is increased by 68%
and the response time
hysteresis and residual birefringence have no degradation.
