Abstract
Dielectric behaviour of a nematic liquid crystal nematic liquid crystal mixture E-24 and its dye doped sample has been investigated in the temperature range 30–58 °C. The dielectric constant (ε′) and the dielectric loss dielectric loss (ε″) of the mixtures (pure and dye doped) have been measured in a frequency range of 100 Hz–10 MHz on a Hewlett-Packard impedance/gain phase analyzer (HP 4194-A). The dielectric study has exhibited relaxation behaviour giving rise to different relaxation frequencies for given temperatures. These frequencies have been used to calculate the relaxation time and activation energies in nematic phase of the pure and dye doped samples.
