Abstract
The treated multiwalled carbon nanotube/silicon nitride (MWCNTs/Si3N4) hybrid fillers were employed to fabricate thermal conductive MWCNTs/Si3N4/epoxy composites. The thermal conductive coefficient of the composites with 45 wt.% treated MWCNTs/Si3N4 hybrid fillers (5 wt.% MWCNTs + 40 wt.% Si3N4) was 2.42 W/mK. The mechanical properties of the composites were optimal with 7 wt.% MWCNTs/Si3N4 hybrid fillers (2 wt.% MWCNTs + 5 wt.% Si3N4). The composites possessed better thermal stabilities than that of native epoxy composites. For the same hybrid fillers loading, the surface treatment of MWCNTs/Si3N4 hybrid fillers exhibited a positive effect on the thermal conductivities of MWCNTs/Si3N4/epoxy composites.
