ABSTRACT: Polymers typically have intrinsic thermal conductivity much lower than other materials. Enhancement
of this property may be obtained by the addition of conductive fillers. In this research, epoxy
nanocomposites with exfoliated graphite nanoplatelets are prepared and characterized. The chosen
approach requires no surface treatment and no sophisticated equipments allowing one to produce
composites on a pilot scale. A significant increase of the thermal conductivity with the increasing
of the graphite fillers content is nevertheless observed on 4 mm thick specimens. Our
results viewed in the latest scientific findings suggest that the choice of resin is an important parameter
to move towards composite materials with high thermal conductivity.
