Electrical resistance of a composite material containing highly conductive graphite flakes is investigated using a computer simulation method in order to improve the electric conductivity.
This simulation shows that resistance of mixture composed of graphite flakes and resin decreases markedly at a certain volume fraction of graphite in resin in same manner as experimental results. Increase of aspect ratio of dispersed graphite flakes decreases a transition threshold and increases the electric conductivity at percolation state. Therefore it is deduced that the electrical conductivity is increased by the introduction of small amount of graphite having a large aspect ratio into resin.
