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

Abstract Photopolymerization induced phase-separation of liquid crystal/polymer mixtures in holographic gratings show promise as switchable Bragg reflectors for optical communication and reflective display applications. The electro-optic properties of such Holographic Polymer Dispersed Liquid Crystals (H-PDLCs) are strongly dependent on polymer morphology and the degree of separation of the LC/polymer mixture. We report scanning electron microscopy, optical polarizing, and electro-optic studies on H-PDLC materials.
