Title
Thermodynamic Parameters of Hexaethylene glycol-Water System using Picosecond Time Domain Reflectometry
Authors
Abstract
The dielectric relaxation measurement of polymers in water mixtures have been carried out over entire concentrations, at temperatures 250C using picoseconds time domain reflectometry technique in the frequency range of 10 MHz to 30 GHz. The complex permittivity spectra of Hexaethylene glycol - water mixtures were fitted using Havriliak-Negami equation. The static dielectric constant (), high frequency permittivity () and relaxation time() for all concentrations have determined using least square fit method. The thermodynamic parameters like free energy, enthalpy(H) and entropy(S) of activation for Hexaethylene glycol-water mixture were studied and reported.
Key Words
Keywords: Polymers, Dielectric Relaxation, time domain reflectometry, static dielectric constant (), high frequency permittivity () , relaxation time ()free energy, enthalpy(H) and entropy(S) etc.
