One way to improve thermal and electrical conductivity of conventional polymers is by combining polymer matrices with highly conductive fillers. This study involves an analysis of electrical and thermal conductivities of nonirradiated and irradiated samples of ethylene vinyl acetate 18 (EVA18) containing expanded graphite (EG) or SDS-EG. Thermal conductivity measurements were at room temperature. An increase in thermal conductivity was found with increasing filler content in all investigated samples, due to ...
