In this study, natural rubber/styrene butadiene rubber (NR/SBR) and NR/carboxylated styrene butadiene rubber (NR/XSBR) nanocomposites with carbon nanotube (CNT) were prepared by a latex compounding method. The dry weight ratio of either NR/SBR or NR/XSBR was fixed to 80/20 and the CNT loading in each blend was varied from 0.1 to 0.4 phr. The nanocomposite latices were cast into sheets on a glass mold and then cured at 80°C for 3 h. The tensile properties (tensile strength, modulus at 300% strain, elongation at break) and dynamic mechanical properties (storage modulus, loss tangent) of the vulcanizates were then evaluated. The results showed that the addition of CNT at a very loading could enhance the tensile strength, modulus at 300% strain and storage modulus of these two rubber bends in a dose dependent manner, except that the tensile strength peaked at an optimum filler level, declining at higher filler loadings, whilst the elongation at break deteriorated. Moreover, the tensile strength and modulus at 300% strain of the NR/XSBR nanocomposites appeared to be higher than those of the NR/SBR nanocomposites at the same CNT loadings.

A computational method based on molecular dynamics simulation has been used to investigate the tribological behavior of carbon nanotube reinforced styrene-butadiene rubber. A three-layer molecular model in which top and bottom layers with Fe atoms and core with styrene-butadiene rubber matrices have been designed. The effect of sliding velocities from 1 m/s to 11 m/s has been studied at an applied normal loading. The properties predicted are abrasion rate and coefficient of friction. The average values of coefficient of friction and abrasion rate decrease from 0.451 to 0.328 and 21.16 to 16.5%, respectively, under sliding velocities of 1 m/s to 11 m/s. The molecular dynamics results show the decrease in coefficient of friction and abrasion rates with increasing sliding velocity.
