Mechanical performance of styrene-butadiene-rubber filled with carbon nanoparticles prepared by mechanical mixing

► We compare influence of carbon blacks and carbon nanotube on properties of SBR. ► We model mechanical behavior of SBR nanocomposites by the micromechanical model. ► Mechanical properties of carbon black/SBR is greatly dominated by bound rubber. ► Mechanical properties of SBR/nanotube is governed by big aspect ratio of nanotube.
