Original Abstract

The objective of this research is to measure and to analyze dielectric properties of KRASOL oligomer materials. The research of material characteristics necessitates the selection of an appropriate analytical method. One of the modern experimental methods is dielectric relaxation spectroscopy (DRS). In general, DRS studies molecular dynamics of current carriers and dipoles. DRS is based on a set of theories and methods dealing with this dynamics. The analysis and subsequent interpretation is based on a detailed observation of temperature dependencies of the relaxation processes prior to and after the ageing process in a broad frequency range. Measurements in the frequency domain were carried out on the Hewlett Packard HP 4284A precision LCR meter using the dielectric test fixture HP 16451B. The sample was analyzed in the temperature chamber, which was specifically developed for this experiment. The position of relaxation maximums matches with the straight-line characteristic and therefore Arrhenius activation law was used for its description and activation energy was calculated.
