Influence of the crystallinity of the alignment layer on the bistability of the surface-stabilized ferroelectric liquid-crystal effect

The influence of the crystallinity of the alignment layers on the electro‐optical behavior of ferroelectric liquid crystals has been quantitatively demonstrated. The degree of crystallization of thin nylon 6.6 alignment layers was varied using thermal anneal methods and determined by Fourier transform infrared spectroscopy. The reaction of an obtained memory state of surface‐stabilized ferroelectric liquid‐crystal samples to small disturbing electric fields decreased when the degree of crystallization of the incorporated nylon 6.6 alignment layers was higher.
