Abstract

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.
