Concentration Dependent Physical Parameters of Ferroelectric Liquid Crystal and ZnOS Nano Material Composite System

Abstract

Inorganic semiconducting ZnOS nano material were doped in the pure Ferroelectric Liquid Crystal and electro-optic as well as dielectric properties have been scrutinized to understand the nature of ferroelectric liquid crystal nano material composite system (FLCNMCS). The nano material changes the characteristics of pure FLC geometry and alters its physical parameters. The physical parameters of FLCNMCS also depend upon the concentration of nano material. In the present paper, change in physical parameters like dielectric permittivity, relaxation strength, activation energy, spontaneous polarization, response time, rotational viscosity etc. due to nano material has been explained in the light of different factors.
