Conductive composites based on exfoliated graphite

  • Published:
Inorganic Materials Aims and scope

Abstract

Conductive composites of exfoliated graphite (EG) and coal-tar pitch have been prepared by mixing the components. The electrical properties of the composites have been studied, and the results have been interpreted in terms of the percolation theory. The threshold EG content for electrical conduction is determined to be ≃ 1.5 wt %, independent of the properties of the pitch and EG.
