Dependence of the electrical conductivity of graphene reinforced epoxy resin
Abstract
The electrical conductivity of graphene reinforced epoxy resin was measured. The conductivity was found to be dependent on the concentration of graphene. A percolation threshold was observed at a graphene concentration of 0.5 wt%. The conductivity increased sharply above the percolation threshold. The maximum conductivity achieved was 10 S/m at a graphene concentration of 5 wt%. The experimental results were compared with theoretical models.
