Research Abstract

Dynamic percolation behavior, which is a transition-like behavior in the electric conductivity due to the filler aggregation and filler network formation at high temperature for the polymer composites filled with electric conductive particles such as nano-carbon, was quantitatively analyzed. The electric conductive microcellular composites filled with small amount of filler were successfully created after controlling the electric conductive filler network structure by applying the dynamic percolation behavior.
