Abstract

The dielectric studies in two nematic liquid crystal mixtures (E-201, E-47) in the frequency range of 50 Hz–1 MHz and theoretically calculated up to the extended frequency range have been investigated. The real and imaginary parts of dielectric constant at low frequencies exhibit a significant contribution of conductivity. The corrected dielectric parameters show Debye-type dispersion with symmetric distribution of relaxation times. Our results indicate that dielectric increment, empirical-factor and static permittivity vary with temperature. A well known Fuoss – Kirkwood method was used to analyze the dielectric parameters.
