Abstract
Multi-walled carbon nanotubes (MWCNTs) were first treated by a 3:1 (v/v) mixture of concentrated H 2SO 4/HNO 3, and then triethylenetetramine (TETA) grafting was carried out. Nano-sized silicon carbide particles (SiC np) were modified by the silane coupling agent. Epoxy nanocomposites filled with hybrid filler system containing TETA-functionalized MWCNTs and silane-modified SiC np were prepared. The investigation on the thermal conductivity of epoxy nanocomposites filled with single filler system and hybrid filler system was performed. Chemical surface treatment is conducive to the enhancement of thermal conductivity of epoxy composites. The thermal conductivity of epoxy composites with hybrid filler system is higher than that of epoxy composites with any single filler system (functionalized MWCNTs or modified SiC np), which is due to the effective combination of MWCNT-to-MWCNT and SiC np-to-SiC np conductive networks. Hybrid filler system could provide synergistic effect and cost reduction simultaneously.
