摘要

AbstractNew material consisting of nematic liquid crystal droplets from 2‐30 μm in radius in a crosslinked UV‐cured polyester resin binder was prepared. Micrographs of the samples were taken in the optical microscope with cross‐polaroids. Reorientation of the droplets by application and removal of an electric field is discussed. Electrooptic properties of the material were measured using polarized light from a helium‐neon laser. Transmittance and response time vs. voltage applied with driving frequency 2 kHz were detected on the oscilloscope and photographed. The response times were: rise time τonshorter than 20 ms at applied voltage higher than 50 V, and decay time τoff= 80 ms. They are a promising feature for this material for a display a
