Abstract
The nematic liquid crystals is considered as a weak electrolyte. The analysis of the time behavior of the transient current flowing through the sample allows the estimation of the mean mobility of anions and cations. The electrohydrodynamic flows are avoided thanks to the application of low voltages. For p-octyloxyphenyl p prime -pentyloxybenzoate the measured values of mobility are mu (perpendicular) equals 0,9 multiplied by (times) 10** minus **6 cm**2V** minus **1 and mu // parallel equals 1,3 multiplied by (times) 10** minus **6 cm**2V** minus **1 s** minus **1 at 326K. The temperature behavior of mobility and conductivity is described by identical activation energies: 0. 48 eV and 0. 16 eV in nematic and isotropic phase respectively.
