摘要：

Epoxy resin filled with carbon materials including graphite nanoplatelets, carbon blacks and carbon nanotubes was synthesized via a liquid mixing method. It was suggested that the conductivity of the composite filled with three fillers was much higher than that filled with only one or two carbon fillers. While the percolation threshold was 1 wt.% and 0.5 wt.% respectively for the composites filled with pure graphite nanopatelets and graphite nanoplatelet/carbon black (mass ratio of 9:1), it was only 0.2 wt.% for the nanocomposites filled with graphite nanoplatelets/carbon black/carbon nanotubes (mass ratio of 7:1:2). The synergistic conductive effect among the three carbon fillers was investigated in detail. (C) 2010 Elsevier B.V. All rights reserved.
