The electrical conductivity of composites obtained by mixing epoxy resin and expanded graphite (EG) nanosheets has been investigated. Conductivity changes of up to I I orders of magnitude were observed as the filler load increased from 0 to 8 wt.%, while the percolation threshold was around 3 wt.%. It was also shown that epoxy/EG composites with intermediate filler contents exhibit a ``phase transition'' from predominantly ``contact conductivity'' to ``tunneling conductivity'' during heating from room temperature to 120 degrees C.
