Abstract

We study nonaqueous emulsions that are composed of liquid crystal and silicone oils. New surfactant molecules are specifically synthesized to stabilize these emulsions. The behavior of the present surfactants is reminiscent of the behavior of classical surfactants used for aqueous emulsions. Depending on their affinity for the liquid crystal or the silicone oils, they may either stabilize silicone in liquid crystal emulsions or stabilize liquid crystal in silicone emulsions. Stabilization of nonaqueous liquid crystal emulsions may be potentially useful as a new method for making electrooptical display instruments known as polymer dispersed liquid crystal devices. It also presents a way to impart specific optical properties to silicone materials traditionally used in various coating applications and in cosmetics.
