| Popis: | New types of heterogeneous systems based on polyethylene or polystyrene or polystyrene matrices containing precious metal powder or ruthenium dioxide were developed. Characterization of these materials included the determination of the dependence of the resistance on the powder content and the dependence of the impedance and phase angle or the capacitance on the powder content at various frequencies and temperatures. The critical parameters of the blending curves were evaluated for various composites. Frequency measurements made it possible to determine the complex permittivity and to show that its real part increased with increasing conductive ingredient content up to a value of about 1600 or more for a frequency of 1 kHz. |
