Effect of Dichroic Dye on Dielectric and Optical Properties of a Nematic Liquid Crystal
Deepa Pal, Prashant Misra, A.K. Misra, Rajiv Manohar and J.P. Shukla

Abstract:
Temperature variation of dielectric loss, dielectric permittivity, dielectric anisotropy and percentage optical transmittance of nematic liquid crystalline sample B08 and its composite with dye have been reported in the temperature range of 30 to 164°C. The dielectric loss and dielectric permittivity have also been measured with variation of frequency. The dielectric studies have been conducted in the frequency range of 1 kHz to 5 MHZ. The thermodynamical parameters have also been calculated by using the dielectric loss data in the frequency range mentioned above. A comparison of dielectric and optical parameters including transition temperature of pure nematic sample with dye mixed liquid crystal indicates that a significant change take place in these properties due to addition of dye in host liquid crystal.
