The effects of the fluorinated monomer with an ethynyl group on the electro-optical properties of polymer-stabilized blue phase liquid crystals (PSBPLCs) were investigated in different polymer systems. In rigid polymer systems, the Kerr constant can be increased by about 27.6%, while keeping a microsecond response time. In soft polymer systems, hysteresis decreased by about 45.5% and residual birefringence can be reduced from 1.85% to 0.6%. The above phenomena exhibited dual functions of affecting the anchoring energy and the viscosity of the system simultaneously. The results provide a potential value for the ethynyl-containing monomers in PSBPLC systems.
研究了含乙炔基的氟化单体在不同聚合物体系中对聚合物稳定蓝相液晶(PSBPLCs)电光性能的影响。在刚性聚合物体系中,克尔常数可提高约27.6%,同时保持微秒级响应时间。在柔性聚合物体系中,滞后现象降低了约45.5%,残余双折射可从1.85%降至0.6%。上述现象展现出同时影响体系锚定能和粘度的双重作用。研究结果为PSBPLC体系中含乙炔基单体提供了潜在价值。
