Dielectric properties of polar fluid mixtures at wide range of temperature and frequency

Abstract

Dielectric property of a liquid is depends upon different parameters such as temperature, frequency, impurities, moisture content and presence of other liquids etc. In this experiment Silicone fluids of different viscosity were used as the dielectric liquid and analar graded dimethyl ketone was used as the solvent and measurements were carried out at various mixture proportions, temperature and frequencies. The experimental values have been verified with the existing literature through the determination of the dipole moments, polarizability. Fourier Transform Infrared Spectroscopy (FTIR) analysis also performed for the verification of the liquid purity. Thus the measured results were employed to arrive at a unified method of calculating the dielectric properties.
