The friction and wear properties of polyamide6 (PA6), polyamide6/carbon nanotube (PA6/CNT) nanocomposites and PA6/maleic anhydride grafted Styrene-ethylene-butylene-styrene (SEBS-g-MA+CNT) nanocomposites was studied by means of a ring-on-block tribometer. The morphologies of the worn surfaces of specimens were observed with a scanning electron microscopy (SEM). All specimen wear increases with increasing load; meanwhile, the friction coefficient decreases. Wear of PA6/CNT is larger than that of PA6. Adding SEBS-g-MA to the PA6/CNT improves the wear resistance. The friction coefficient of PA6/CNT is slightly less than that of PA6 at various loads. The friction coefficient of PA6/(SEBS-g-MA+CNT) is the lowest among PA6, PA6/CNT and PA6/(SEBS-g-MA+CNT).
