| Cílem práce bude příprava kompozitů na bázi polyolefinů a uhlíkových nanotrubiček. Bude zkoumána elektrická a tepelná vodivost, perkolační chování, mechanické vlastnosti a tepelná stabilita v závislosti na obsahu plniva a způsobu přípravy. Elektrická vodivost bude u těchto kompozitů měřena v závislosti na frekvenci, protažení a teplotě. | |
| Annotation: | |
| The aim of this study will be preparation of composites based on polyolefins and carbon nanotubes. Electrical and thermal conductivities, percolating behavior, mechanical properties and thermal stability will be investigated as a function of the filler content and preparation method. The electrical conductivity of these composites will be measured as a function of frequency, elongation and temperature. | |
