Effect of Polarized Light Polymerization on Reflection Band Tunability in Polymer-Stabilized Bimesogenic Cholesteric Liquid Crystal Devices

摘要

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