| Abstract: | Graphene oxide (GO) and silicon dioxide (SiO2) nanoparticles have been hybridized for improving the mechanical and dynamic mechanical properties of nitrile rubber (NBR). SiO2 nanoparticles were homogeneously dispersed on the surface and between layers of GO, and the new hybrid nanoparticles formed (GO/SiO2) had better thermal stability than GO. To evaluate the mechanical properties, GO/SiO2/NBR nanocomposites were prepared by solution blending and mechanical solution methods. It was observed that tensile strength increased in a larger grade in GO/SiO2/NBR nanocomposites than that in GO/NBR and SiO2/NBR nanocomposites, while the elongation at break only changes smoothly. Moreover, dynamics measurements also indicated that the elasticity increased after adding GO/SiO2 hybrid nanoparticles in NBR. From morphology's analysis of GO/SiO2/NBR and GO/NBR nanocomposites, it is was conclude that the hybridization of the GO/SiO2 was the determining factor for the reinforcement of the mechanical properties and elasticity of the NBR. © 2017 Wiley Periodicals, Inc.
