“…The results indicate that the mechanical properties of the hybrid filler rubber composites are much higher than that of the SBR/SiO 2 and SBR/GO composites. The addition of SiO 2 and GO successfully enhances the abovementioned properties due to reinforce ability of the fillers which is associated with the higher modulus and rigidity of the blend vulcanizates . Although, SBR/DeVulcNR shows poor mechanical properties but in the presence of SiO 2 and GO, the composite shows excellent mechanical properties due to rubber–filler interaction occurs only in the presence of DeVulcNR.…”

Ethoxy functionalized devulcanize natural rubber (DeVulcNR) is used as compatibilizer for silica/graphene oxide (SiO2@GO) hybrid fillers in the styrene butadiene rubber (SBR) to fabricate SBR composites. The dispersion behavior of SiO2@GO hybrid filler was investigated through scanning electron microscopy (SEM) analysis of the tensile fracture surface along with the broken rubber surface developed by plunging into liquid nitrogen. The rubber–filler interfacial interactions were evaluated through the measurement of equilibrium swelling experiment, fraction of immobilized polymer chain by DSC study, FTIR analysis, and molecular dynamics simulation. The results reveal that in the presence of DeVulcNR, the rubber–filler interaction is enhanced compared with that of the control formulations containing only SBR. SiO2@GO hybrid‐filler shows synergistic effect on the mechanical properties of the composites in the presence of DeVulcNR. The improved mechanical properties of the SiO2@GO hybrid filler rubber composites may be due to chemical interaction among the functional groups of SiO2 and GO with the DeVulcNR. Further, XRD study indicates that there is no significant layer‐by‐layer restack of GO in the SBR/DeVulcNR composites. The higher storage modulus and lower tan δ of the SiO2@GO hybrid filler rubber composites show superior interfacial interaction between rubber and filler compared with that of the control formulations.

The effect of interface property on the mechanical behavior of silica-polybutadiene composites is systematically investigated via combined experimental and dynamics simulation. In experiment, the interface property is controlled by SiO 2 particle size, silane coupling agents, and silane grafting density. The effects of these control parameters on the vulcanization kinetics, tensile strength, and dynamic mechanic properties are investigated and discussed. Both the experimental and simulation studies reveal the pivot role of filler-polymer interface on the mechanical reinforcement. Simulation study reveals that the constrained polymer layer (12 nm) surrounding the silica particles shows increased stress from 30 to 230 MPa, which is identified as the major reason for the overall enhancement of 100% modulus from 0.8 to 1.6 MPa. The molecular mechanics of interface from simulation is well correlated to the experimental results in this study, which provides a molecular level understanding of the relationship between interfacial interaction and mechanical reinforcement.

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.
