Four kinds of deep eutectic solvents (DESs) based on choline chloride and polyols were prepared. Density, viscosity and conductivity of the four DESs were measured as functions of temperature in the range of 303～343 K. The results show that the densities of the four DESs sare linearly dependent on temperature. Viscosities decrease with increasing temperature, and conductivities increase rapidly with increasing temperature,both obeying the Arrhenius exponential law. The activation energy of viscosity and conductivity were calculated with the Arrhenius formula. The electrochemical windows of the four DESs were also tested by using cyclic voltammetry at 333 K.
