Styrene-butadiene rubber (SBR)/carbon nanotube (CNT) nanocomposites were prepared by using Polystyrene (PS) coated CNTs as a master batch.  The effect of coated CNT loading on the mechanical properties and electrical conductivity of the nanocomposites was investigated and compared with the pristine CNT.  The dispersion of the CNT was evaluated using FESEM. It shows the coating of PS improved the dispersion of CNTs in SBR at low loadings and further increased the mechanical properties and volume resistivity.
