摘要：

The conditions to form a conductive network in carbon black filled epoxy resin were examined. It was found that the formation is controlled by particle-particle interaction which can be influenced by shear forces or by the ionic concentration of the resin. Therefore the network morphology and thus the percolation threshold depends strongly upon the processing route. On best conditions the percolation threshold was reduced to 0.06 vol.-%. That a continuous network can form with such a low volume fraction can be explained by the fractal dimension of agglomerates the network is made of.
