The graphite nanofiber (GNF) and carbon black filled high-density polyethylene (HDPE) hybrid nanocomposites were prepared by solution mixing and melt blending techniques. The effect of addition of GNF on the positive temperature coefficient (PTC) behavior of the nanocomposites was investigated. The incorporation of small amount of GNF into HDPE/CB composites showed a significant improvement in PTC intensity and repeatability of the hybrid nanocomposites. The maximum PTC intensity was observed for the HDPE/CB/GNF (80/20/0.25) nanocomposite with a relatively low room temperature resistivity.
