Polymer-Stabilized Reflective Cholesteric Displays: Effects of Chiral Polymer Networks on Reflectance Properties

Abstract

A white reflecting polymer-stabilized cholesteric textured liquid-crystal cell was created by incorporation of chiral methacrylate polymer networks. The position and stereochemical configuration of the chiral centers plays an integral role in the observed reflection spectra. Chiral polymer networks with chiral centers separated from the polymer backbone and that unwind the cholesteric helix pitch produce the broadest reflection band in these LC mixtures.
