摘要：
The complex permittivity spectra of binary mixtures of methoxy polyethylene glycol (Polyethylene glycol monomethylether 350) and water over entire concentrations and at different temperatures have been measured using time domain technique in the frequency range of 10 MHz to 30 GHz. The spectra have been fitted to Cole-Davidson model using non linear least square fit method to obtain the dielectric parameters. The non linear behaviour of dielectric parameters suggest intermolecular interaction among the unlike molecules. Excess properties and Bruggeman factor confirm the contribution of hydrogen bonding interactions among the solute-solvent mixtures. Thermodynamic properties of these binary mixtures are also discussed.
