Studies of the Dependence of the Electra-Optical Characteristics of Polymer Dispersed Liquid Crystal Films on Curing Temperature

Abstract

The electro-optical characteristics of polymer dispersed liquid crystal (PDLC) films were studied as a function of the polymer's curing temperature. The results show the film, having a smaller and more uniform LC droplet size, produced at higher curing temperatures, exhibits not only a steeper electro-optical response curve but a better transmission contrast between on- and off-state. The transient electro-optical response time of PDLC films is also a strong function of the LC droplet's sizes.
