▎ 摘　　要

This work analyzes the electrical heating by Joule's effect of epoxy resins doped with carbon nanotubes (CNTs), graphene nanoplatelets (GNPs) or a combination of both. The main objective is to obtain heat-dissipating materials with relatively high electrical conductivity for future applications in smart electrical and electronic devices. In addition, a thermal and mechanical characterization of the composites is carried out in order to study the combined effect of CNT and GNP. Different nanocomposites were manufactured by athree-roll mill process, as thedispersion technique. A thermal infrared camera was used to acquire the temperature's increment due to Joule's heating. CNT addition induces an important increase in electrical conductivity, which has associated an important heating. The combined addition of both nanofillers, GNP and CNT, scarcely modifies the electrical conductivity, but it induces an important increase in thermal conductivity of the composites. This helps leadto a more homogeneous heating and therefore a more efficient heat dissipation.
