Paper Abstract

Cholesteric liquid crystals (CLC) with a specific confinement conditions are known to form bubble domain (BD) texture. We have developed the CLC BD texture stabilized with a small amount of polymer. CLC bubbles of a BD texture self-assemble into domains with a hexagonal ordering and optically perform as a diffraction grating. By stabilization of the BD texture with a polymer we have improved optical quality of the diffractive CLC layer and have increased its mechanical stability. We discuss details about samples preparation, Bragg diffraction, electro-optical performance and present results of scanning electron microscopy (SEM) morphological study of the polymer network formed in the bulk of the diffractive liquid crystal layer.
