A New Model of Dielectric Constant for Binary Solutions

Abstract

From the group statistical theory, and with a pseudochemical reaction mechanism, a new universal equation is proposed to calculate the dielectric constant for binary solutions. The simple form of the new model makes it convenient to use and all its parameters have obvious physical meanings. With this model, we explained the experimental phenomena and empirical rules in cited works. Tested by 225 kinds of binary systems, the overall average relative deviation at 4228 data sets is 0.775 % and the results show that this new model is more accurate than the cited models. This model is especially suitable for associative and asymmetric systems.

Dielectric mixtures: electrical properties and modeling

“…One can also include the mixture examples in biological systems where the dielectric spectroscopy has been one of the tools to obtain information about the structural and dynamical behavior [146,147,10,148]. Similarly, work on liquid-liquid mixtures can be found in the literature [149,150,151,152,153,154,155,156,157,158,159,160,161,162,163,164,165]. The dielectric spectroscopy technique has been found powerful for investigating polymer-polymer mixtures [166,167,168,169,170,171,172,173,174,175,176].…”
