Polymer dispersed nematic liquid crystal films: The density ratio and polymer’s curing rate effects

Abstract

The effects of the density ratio and the polymer’s curing rate on the characteristics of polymer dispersed nematic liquid crystal (NLC) films are reported. Measurements indicated that the slope of the electro-optical response curve, which determines the film’s multiplexing capability, is a strong function of the uniformity of the NLC droplet’s size. Both the density ratio and the polymer’s curing rate are shown to be crucial in the production of a more uniform droplet size. Polymer dispersed LC films, suitable for different applications, can be produced by varying the curing rate.
