More Information
Summary:The microscopic state of water in dielectric liquids relates to the hydrogen bonding energy between the water molecules and the polarization site of the liquids. It has been reported that the dc conductivity of dielectric liquids including water is estimated by the hydrogen bonding energy. In this report, it is shown that the molecular hindrance relating the length of the side chain does not affect the microscopic state of water, but the conductivity decreases according to the length of the side chain. Our model of the effect of the water cluster on conductivity is the conductive bridge formed by the water cluster. In this model the molecular hindrance disturbs the formation of the water cluster bridge.
