Morphology of Holographically-Formed Polymer Dispersed Liquid Crystals (H-PDLC)

摘要

Photopolymerization induced phase-separation ofliquid crystal /polymer mixtures in holographic gratings showpromise as switchable Bragg reflectors for opticalcommunication and reflective display applications. The electro-optic properties of such Holographic Polymer Dispersed LiquidCrystals (H-PDLCs) are strongly dependent on polymermorphology and the degree of separation of the LC/polymermixture. We report scanning electron microscopy, opticalpolarizing, and electro-optic studies on H-PDLC materials.
