Original Abstract
Dielectric Relaxation Spectroscopy (DRS) is a powerful tool for the investigation of materials. DRS is based on the measurement and evaluation of the response of electric dipoles, either induced or permanent, and weakly bound electric charges to the application of external electric field. The main information that can be extracted from the DRS is related to the molecular dynamics of dipoles. Therefore, DRS finds use in those fields where mobility of individual molecules, segments of molecules or separate chemical bonds or changes in chemical composition is involved - monitoring of hardening or swelling processes, analysis of glass transition, applications in degradation and ageing of materials based on disappearance or emergence of dipoles and charge-carriers. Current experimental equipment available in the Department of Physics, allowing measurements in the frequency range 100 Hz - 3 GHz and in the temperature range 10 - 500 K, are presented.
