Optical and Thermal Characterization of Binary Mixtures of Liquid Crystals

What is it about?

We report the results of our studies on the optical and thermal properties of the mixture of cholesteryl nanonate, cetyl-dimethyl-ethylammonium bromide, and ethylene glycol, which exhibits very interesting liquid crystalline mesophases like cholesteric (N ∗ ) and induced smectic phases, such as SmA, SmC ∗ , SmE, and SmB, sequentially when the specimen is cooled from its isotropic liquid phase. These phases have been character- ized by using differential scanning calorimetric, X-ray diffraction, and optical texture studies. The pitch of the cholesteric phase is discussed. The temperature variation of optical anisotropy, electrical conductivity, ultrasonic velocity, molar, and adiabatic compressibility has also been discussed.
