P‐165: Effect of Polarized Light Polymerization on Reflection Band Tunability in Polymer‐Stabilized Bimesogenic Cholesteric Liquid Crystal Devices

Abstract

This work demonstrates approach for improvement of electrooptic performance and light reflectance properties of electricallycontrolled reflective heliconical cholesteric liquid crystal (CLCOH) textures. A noticeable increase of the electric field range which supports the CLCOH texture is demonstrated by using photo polymerization with polarized UV light. Such performance improvement broadens the scope of potential applications of CLCOH materials in electro-optical devices.
