Electro-optic effect in mixture of liquid crystalline materials

T.N.Govindaiah

In the presentwork, our investigation is to study on the optical and electrical properties of multi-component system of cholesteryl nonanoate (CN), Cetyl-dimethyl-ethylammonium bromide (CDEAB) and Ethylene glycol (EG). Mixtures of these molecules exhibits a liquid crystalline cholesteric, SmA, SmC, SmE and SmB phases sequentially when the specimen cooled from its isotropic phase. These phases have been characterized by using microscopic technique. The temperature variations of optical transmittance have been discussed. Temperature dependent electro-optical phase transition behaviors of the given molecules have been discussed
