The need of high performance integrated circuits and high power density communication devices drives the development of materials enhancing the conductive performances by carbon nanoparticles. Among nanocomposites, the ternary hybrid carbon nanotubes/graphene nanoplatelets/polymer composites represent a debatable route to enhance the transport performances.In this study hybrid ternary nanocomposites were manufactured by direct mixing of multiwalled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) at a fixed filler content (0.3 wt.%), but different relative combination, within an epoxy system. MWNT/epoxy nanocomposites were manufactured for comparison. The quality of dispersion was evaluated by optical and scanning electron microscopy (SEM).
