摘要：

Graphite-like carbon nitride (OCN) synthesized by partial oxygenation was decorated with lipophilic oleic diethanolamide borate (ODAB) groups via a reflux reaction. The as-modified ODAB-OCN nanosheets could achieve a high degree of dispersion in paraffin oil due to the intercalation of oil-friendly ODAB groups between the nanosheet layers. Notably, the results of the friction experiments revealed that ODAB-OCN, a lubricant additive, possessed excellent tribological properties. Unlike the results for pure oil, the average friction coefficient and wear rate for 0.20 wt% ODAB-OCN included in the oil decreased by 22.7% and 90.8%, respectively. This work will be of great significance for the application of graphite-like carbon nitride (g-C3N4) as an oil-based lubricant additive.
