Dependence of the electrooptical properties of polymer-dispersed vertical aligned liquid crystals on the surface affinity of the liquid crystal and monomer

摘要

We studied the dependence of the electrooptical properties of polymer-dispersed vertical aligned liquid crystals on the surface affinity of the liquid crystal and monomer. The liquid crystal mixture with a smaller contact angle formed more cylindrical droplet and showed uniform vertical orientation of liquid crystal molecules. On the other hand, the liquid crystal mixture with a greater contact angle formed spherical droplet and liquid crystal orientation was deformed near the polymer boundary, resulting in a light leakage between crossed polarizers.
