A Study of Electro-optical Properties of Polymer Dispersed Liquid Crystal Films Prepared by UV and Heat Dual Curing
This paper reports studies on the electro-optical properties of polymer dispersed liquid crystal (PDLC) films with UV and heat dual curing. These films consist of micron-sized droplets dispersed in a polymer matrix. They were prepared according to the polymerization induced phase separation that initiated by a two-stepped UV curing and heat curing process, that is, they were cured by UV radiation first and then by heat. It was demonstrated that the heat curing process increased the driving voltage, the contrast ratio and the rise time (τR) of the films, but decreased the decay time (τD) significantly. Further more, the threshold and saturation voltages of the films, together with the contrast ratio,decreased with increasing the content of the heat curable monomers.
