In this study, a single-layered Ti₃C₂ hybrid SiO₂ filler (Ti₃C₂-h-SiO₂) was proposed to fabricate high-performance styrene-butadiene rubber (SBR) elastomer composites. It was found that incorporating SiO₂ not only facilitated the uniform dispersion of Ti₃C₂-h-SiO₂ in the SBR matrix but also endowed the surface of Ti₃C₂-h-SiO₂ with nano protuberances for immobilizing more rubber chains, resulting in the improvement of the interfacial interaction between Ti₃C₂-h-SiO₂ and SBR matrix. Thus, the tensile strength of the SBR/Ti₃C₂-h-SiO₂ elastomer composite was reinforced by 174% compared with the unfilled SBR. Moreover, the wet skid resistance and rolling resistance of the SBR/Ti₃C₂-h-SiO₂ elastomer composite were also remarkably improved. Noteworthily, the exceptional thermal conductivity (0.401 W m⁻¹ k⁻¹) and electrical conductivity (4.87 × 10⁻⁴ S m⁻¹) of the SBR/Ti₃C₂-h-SiO₂ elastomer composite were comparable to the SBR/reduced graphene oxide (rGO) elastomer composite, implying that the conductivity of Ti₃C₂-h-SiO₂ may be competitive with the rGO.
