Computation of Dielectric Constant and Loss Factor of 1, 3-Diethoxymethyl Imidazolium Hexaflurophosphate [Dietmeim] [PF6]

Abstract

Ionic liquids are receiving more and more interest because of their unique properties.  Based on these properties, a multitude of applications are being developed. Although ionic liquids are applied in many fields and considered to be very potential to meet the special need for different projects, the lack of systematic and mechanistic understanding of the properties is a bottle neck for its progress. However, this research on ionic liquids will determine the frequency level that the dielectric constant and loss factor will be more effective .The Cole-Cole relaxation equation was derived and the values for the dielectric constant and loss factor of 1,3-diethoxymethyl Imidazolium hexaflurophosphate [DiEtMeIm][PF₆] were determined. The computation was done within the frequency of 0.1GHz to 10GHz and temperature between 5℃ to 65℃. The result obtained shows that the dielectric constant and loss factor of 1,3-diethoxymethyl Imidazolium hexaflurophosphate [DiEtMeIm][PF₆] were higher at low frequency (i.e. F = 0.1GHz) and decreases as the frequency increases. The dielectric constant also increases with increase in the temperature except at 0.1GHz. The increase in the dielectric constant of the ionic liquids may be due to all the phase change of the ionic liquid. The loss factor was small for all frequencies and temperatures. This may be due to the fact that the ionic liquids consumed less energy when subjected to an applied field. However, chemical industry and other industries that use IL for their production can do so at higher frequencies. This is because higher frequencies have the lowest value of the dielectric constant. Higher dielectric constants have the tendency to breakdown more easily when they are subjected to intense electric fields than lower dielectric constants.
