在本文中，我们报告的铁电液晶的近晶层结构的抗热震性显着增强的定向细聚合物纤维，这是由光聚合诱导相分离形成的稳定。发现具有垂直于近晶层排列的此类聚合物纤维的近晶层结构即使在复合膜冷却至低于手性近晶C-至-晶体相变温度的-15 ° C或加热至高于手性向列相至-各向同性相变温度的100°C之后也不产生Z字形缺陷。
In this paper, we report the marked enhancement of thermal shock tolerance of smectic layer structures of ferroelectric liquid crystal stabilized by aligned fine polymer fibers, which were formed by photopolymerization-induced phase separation. It was found that a smectic layer structure with such polymer fibers, which are aligned perpendicular to the smectic layer, generates no zigzag defects even after the composite film is cooled to -15°C, which is lower than the chiral smectic C-to-crystal phase-transition temperature, or heated to 100°C, which is above the chiral nematic-to-isotropic phase-transition temperature.
