摘要：

The electrical and thermal conductivity of the ternary epoxy composites (CMs) with two-component fillers, multiwall carbon nanotubes (MWCNT)/TiO2, and MWCNT/carbonyl iron (Fe) have been investigated. The increase of the percolation threshold was found for the ternary CMs compared to MWCNT/epoxy CMs. At MWCNT content higher than 3 wt.%, the conductivity of the ternary CMs is much higher than in MWCNT/epoxy. The temperature dependencies of the electrical resistivity were analyzed within the fluctuation-induced tunneling conductivity model. It was found that adding of two-component fillers MWCNT/TiO2 or MWCNT/Fe into epoxy promotes smaller changes in thermal conductivity compared to the two-phase MWCNT/epoxy composites.
