Měření a vyhodnocení elektrických vodivostí pelet PANI a PANI/FYLOSILIKÁT

Abstract

This barchelor thesis deals with specific conductivity measurement of polyaniline and its composite with titanium oxide (TiO2). The layered silicate kaolinite was used as carrier of TiO2 nanoparticles. Samples of polyaniline and its composite were prepared in the form of powder. Then the pellets for specific conductivity measurement were made under pressure. The main targets of this work were: • Optimization of pellets preparation. • Calibration and testing of measuring device and measuring of pellets specific conductivity. Theoretical part deals with present knowledge in the field of this research and also it states theoretical basis of performed measurements. Experimental part contains the comparison of the measured specific conductivities and measurement of pellets in the DC an AC mode of electric current. The optimization of specific conductivity measurement methods was made.
