The influence of cyano compound on liquid crystal blue phase range

Abstract

Liquid crystal blue phase (BP) is interesting for fast light modulators and tunable photonic crystals. In this study the influence of mixture composition on the thermal stability of BP was investigated, especially the influence of cyano compound addition. The relationship between polymer stabilization possibility and cyano dopant was examined, too. It was shown that the cyano compound is not necessary to create blue phase and has no effect on polymer stabilization of blue phase. Full Text: PDF References H. Kikuchi, M. Yokota, Y. Hisakado, H.
