Light Switching Characteristic of Reverse Mode Type (polymer/liquid crystal) Composite Films using UV Curable Liquid Crystal monomer II

Abstract

We prepared the (polymer/liquid crystal) composite films using nematic LC and UV curable LC with aligning treatment, which exhibited the characteristics of the reverse mode. In this study, we investigated the light switching characteristics of the composite films consisting of 4'-cyanophenyl 4-acryloyloxy benzoate (ACPBCN) as a monomer and E7. The composite film would be driven at less 20 Vrms, and the hysteresis was improved by the addition of diacrylate monomer (PBAHB).
