Variations of Entropy and Thermal Diffusivity Effect on the Morphology of Induced Chiral Smectic Phase of Liquid Crystals

Abstract

We report the results of our studies mainly focus on thermal and optical properties of a system comprising the ternary system of organic molecules such as Curcumin, dodecanol and Ortho phosphoric acid. Mixture of these molecules exhibits a very interesting induced SmA-SmC and SmC* phases respectively at different temperatures and at different concentrations. In our studies we discuss the estimated values of entropy and thermal diffusivity effect on morphological phase behaviour of liquid crystals towards the isotropic phase transition with the help of conductivity and polarizability data. Wave length dependent refractive indices are helps to study the Sellmeier constants A and B and thermo-optical coefficients have also been discussed.
