A simple approach to decorate multi-walled carbon nanotube (MWCNT)-reduced graphene oxide (RGO) hybrid nanoparticles with zinc oxide (ZnO) nanorods is developed to improve the electrical and mechanical properties of poly(vinyl chloride) (PVC)/MWCNT-RGO composites. The ZnO nanorods act as joint in three-dimensional (3D) MWCNT-RGO networks and the hybrid particles strongly interact with PVC chains via p-pi stacking, hydrogen bonds, and electrostatic interactions, which we confirmed by scanning electron microscopy (SEM) and Raman analysis. By introducing the ZnO nanorods, the RGO-ZnO-MWCNT hybrid particles increased 160% in capacitance compared with MWCNT-RGO hybrids. Moreover, the addition of RGO-ZnO-MWCNT to PVC resulted in the mechanical properties of PVC being enhanced by 30.8% for tensile strength and 60.9% for Young's modulus at the loadings of 2.0 weight percent (wt.%) and 1.0 wt.%, respectively. Meanwhile, the electrical conductivity of PVC increased by 11 orders of magnitude, from 1 x 10(-15) S/m to 1 x 10(-4) S/m for MWCNT-ZnO-RGO loading at 5.0 wt.%.
