摘要：
The encapsulation of ferroelectric liquid crystal droplets in a polymer film provides a convenient method to get fast switching, flexible electro-optic light shutters. The polymer-dispersed ferroelectric liquid crystal films can be formed by photopolymerization due to a polymerization-induced phase separation. A uniform orientation of the liquid crystal is obtained by shear flow during this process. Our studies concerning the influence of the preparation parameters on the electro-optic properties show that a bistable electro-optic behavior can be achieved for high polymerization rates and low shear velocities.
