Single wall carbon nanotubes (SWNTs) present interesting tribological properties under boundary lubrication at ambient temperature. Used as additives to polyalphaolefin (PAO) base oil, they lead to a drastic decrease of both friction and wear of antagonist steel surfaces. These results are obtained with only 1 wt% of nanotubes dispersed in oil but with a minimal contact pressure of 0.83 GPa indicating that a structural modification is necessary for such improvements. Characterization of nanotubes by analytical TEM and Raman spectroscopy before and after friction is used to understand how nanotubes behave in the contact area.
