In this paper, the self-made MoS2 nanosheets were attempted to be modified with oleic diethanolamide borate (ODAB) through a simple one-step route. The as-modified MoS2 nanosheets were confirmed by a series of characterizations. The results showed that the MoS2 nanosheets could be chemically well capped by ODAB to form C-S bonds. Furthermore, the tribological experimental results indicated that the ODAB-MoS2 nanosheets as lubricant additives could improve the friction properties of base oil. At the optimal adding content of 0.06 wt%, the average friction coefficient, average wear scar diameter and extreme pressure performance of the ODAB-MoS2-based oil were decreased by about 27.9%, 22.9% and 17.4% as compared to base oil, respectively. Finally, the friction mechanism was discussed and proposed. (C) 2018 Elsevier B.V. All rights reserved.
