The influence of cyano compound on liquid crystal blue phase range

Abstract

A liquid crystal blue phase (BP) is interesting for fast light modulators and tunable photonic crystals. In this study we investigated the influence of mixture composition on thermal stability of BP, especially the influence of cyano compound addition. The relationship between polymer stabilization possibility and cyano dopant was also examined. It was shown that the cyano compound is not necessary to create a blue phase and it has no effect on polymer stabilization of a blue phase. © 2012 Photonics Society of Poland.
