摘要：

The aim of the research project was to investigate and maximize the thermal conductivity of polymer compounds with low filler content (<30vol%). The study focused on the effect of the matrix material, the filler type, the processing method and the interaction of the fillers. It was concluded that compression-moulded samples have higher thermal conductivity than injection-moulded samples due to the segregation effect and the orientation of the anisotropic fillers. Conductivity can be improved by adding fillers with higher thermal conductivity, and also by combining, or hybridizing the fillers. A synergetic behaviour between hexagonal boron-nitride and talc which improved thermal conductivity was found.
