Paper Abstract

It is experimentally investigated the dispersion of the dielectric permittivities in the frequency range of 1 kHz divided by 100 MHz in both nematic and isotropic phases of binary mixtures of liquid crystals with different molecular lengths. Two low-frequency relaxation processes related to the dielectric relaxation of the mixture components are separated. The relaxation times and the nematic potentials of each components are determined and compared with molecular sizes.
