Electrical Properties of Graphene Filled Natural Rubber Composites

Abstract

Thermally reduced graphene oxide (graphene) filled natural rubber (NR) composites were fabricated by melt mixing method. Dielectric constant, dielectric loss and a.c conductivity data of the NR composites are reported. Highest conductivity of 3 x 10 -4 S/m was obtained for the composite with 3 wt. % graphene with initial electrical percolation at a loading of 0.5 wt. %. High conductivity in the composite with 3 wt. % graphene is accounted by its homogeneity as observed in SEM micrographs.
