THE DC CONDUCTION MECHANISM OF ETHYLENE GLYCOL WATER SOLUTIONS

Dorota Nowak-Woźny - Tadeusz Maczka

   The effect of temperature and water content in ethylene glycol water solutions upon the electrical characteristics was studied in some details. The temperature was raised from room temperature up to about 380 K. It was suggested that the dependence between conductivity and temperature could be described by an exponential relation with the exponent depending on the potential barrier and temperature. It was supposed that the calculated potential barrier (0.2 eV to 1.1 eV) was associated with the motion of OH-groups.

Keywords: DC conduction, potential barrier, charge transport, ethylene glycole
