The principal aim of this thesis is the investigation of the electrical properties of conducting pigments provided by Merck KGaA. These pigments are generally micron-sized mica particles coated with a transparent conducting oxide (TCO) and are conventionally dispersed in a polymer matrix at varying volume fractions to form composite structures. To measure the electrical properties of composites and powder materials is not easy since one cannot simply attach terminals as in the measurement of bulk materials. We therefore turn to high frequency techniques, which are capable of measuring composites and powders of conducting particles, but are also capable of measuring non-conducting particles. This thesis therefore has three main themes; 1) the development and use of high frequency measurement techniques for the application to Merck pigments, 2) the investigation of the fundamental electrical properties of TCOs, and 3) the study of the complex electrical behaviour of composites.
