"This work deals with electrical and dielectrical properties of polymer - carbon black composites prepared from the solution directly poured into Petri dishes and by the method of spin coating. The solutions of polystyrene in toluene were used for polymer matrix. The carbon black agglomerates were pulverized and dispersed by mechanical rotational homogenizer and by ultrasonic homogenizer. Two kinds of carbon black were used for the samples preparation. 1. Dry carbon black. 2. Carbon black without ions which were extracted in water. Measurements were carried out on the samples with the thickness 0,05 - 0,2 mm with carbon black content from 2 w% to 8 w%. Electrical measurements were carried out at temperatures 20 - 100 C by the method of impedance analysis in the frequency region 102 - 106 Hz both in normal and planar direction and by the method of van der Pauw. The carbon black agglomerate structures were studied by optical and AFM microscopy."@en . . . "6"^^ . . "Lipt\u00E1k, Jan" .
