Abstract
The polymer morphology in Polymer Stabilized Cholesteric Textures(PSCT) film were investigated by the direct observation with scanning electron microscopy(SEM) in order to clarify the relation between polymer morphology and and electro-optic properties of the PSCT film. The SEM photograph revealed that the polymer morphology consisted of spherical particles with submicron order diameter, which three-dimensionally networked each other. The results indicate that the particle diameter and network density varied with the polymerization process and determining the electro-optic properties of PSCT film. It is noted that the polymer morphology with the large particle diameter and low network density was formed by low power and long term UV radiation process, giving to the film with the good electro-optic properties, i.e., low driving voltage, narrow hysteresis width and high contrast ratio.
