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 with sub-millisecond response speed, optical isotropy and without alignment process characteristics, in the display and photonic devices have a wide range of applications. In this paper, a multi-polymer material doping system based on polymer stabilized blue phase liquid crystal was studied. The driving voltage of the polymer stabilized blue-phase liquid crystal can be drastically reduced by doping N-vinylpyrrolidone (NVP) and polyaniline graphene oxide (G-PANI). After optimizing the dopant ratio, the Cole constant of the multi-doped polymer stabilized blue phase liquid crystal material is increased by 68% without negatively impacting the material’s response time, hysteresis and residual birefringence.
