Abstract

ABSTRACT Graphene oxide (GO) and silicon dioxide (SiO 2 ) nanoparticles have been hybridized for improving the mechanical and dynamic mechanical properties of nitrile rubber (NBR). SiO 2 nanoparticles were homogeneously dispersed on the surface and between layers of GO, and the new hybrid nanoparticles formed (GO/SiO 2) had better thermal stability than GO. To evaluate the mechanical properties, GO/SiO 2 /NBR nanocomposites were prepared by solution blending and mechanical solution methods. It was observed that tensile strength increased in a larger grade in GO/SiO 2 /NBR nanocomposites than that in GO/NBR and SiO 2 /NBR nanocomposites, while the elongation at break only changes smoothly. Moreover, dynamics measurements also indicated that the elasticity increased after adding GO/SiO 2 hybrid nanoparticles in NBR. From morphology's analysis of GO/SiO 2 /NBR and GO/NBR nanocomposites, it is was conclude that the hybridization of the GO/SiO 2 was the determining factor for the reinforcement of the mechanical properties and elasticity of the NBR. © 2017 Wiley Periodicals, Inc.
