Fyzikální vlastnosti montmorilonitu plněného polyanilínem

Abstract

This thesis focuses on describing and measuring of physical properties of the composite material montmorilonite doped by polyaniline. The theoretical part describes structure of the investigated material, there are also described the electrical properties of dielectrics in the stationary and alternating electric field. The experimental part of this thesis deals with measuring the mechanical properties of the material, analyzing the structure of the samples under metallographic and electron microscope, measuring DC and AC voltage of specific electrical conductivity depending on the age of samples, followed by measuring the pressure dependence of the electrical resistivity of the samples, the measuring the parameter of impulse voltage resulting from the application of the impulse load and the measuring of temperature dependence of the specific conductivity. Also, the thesis deals with the possibilities of using the various contacts for potential technical applications.
