Exploring dielectric relaxation in 1,2-propanediol and 1,4-dioxane binary mixtures: time-domain reflectometry analysis

This study investigates dielectric relaxation in binary mixtures of 1,2-propanediol and 1,4-dioxane using time-domain reflectometry. The dielectric parameters, including the static dielectric constant, relaxation time, the Kirkwood correlation factor, excess properties, thermodynamic parameters, and Bruggeman factor, are analyzed to study molecular dynamics, dipole orientation, and intermolecular interactions within the mixture. The experimental results provide insights into the dielectric behavior of the binary system, with implications for various applications in material science, chemistry, and chemical engineering. The Luzar theory is applied to study the hydrogen bonding interaction in alcohols mixture. The results have been compared with our previously published work N.P. Garad et al. to study the effect of number of carbon atoms on dielectric properties.
