Electrical and thermal properties of the hybrid composites, prepared using reduced graphene oxide (rGO), multi‐walled carbon nanotubes (MWCNTs), and Poly (methyl methacrylate) (PMMA) have been investigated. In this hybrid composite, the effect of rGO wt.% in MWCNTs/PMMA composite has been investigated. The investigation demonstrates that the rGO–MWCNTs/PMMA hybrid composite achieved considerable improvements in electrical properties compared to the MWCNTs/PMMA and rGO/PMMA composites. The hybrid nanocomposite exhibits a percolation threshold of around 0.743 wt.% which is less than that of MWCNTs/PMMA ( p c = 0.838 wt . % ) and rGO/PMMA ( p c = 1 wt . % ) composites and has a maximum conductivity of 1.546 × 10 −1 S cm −1 with a filler content of 6 wt.% rGO. The experimentally observed improved electrical and thermal properties as a result of increased rGO wt.% in MWCNTs/PMMA are attributed to a synergistic effect of MWCNTs and rGO. The experimentally observed physical properties of the rGO–MWNTs/PMMA nanocomposite suggest it as potential material for future applications.
