The dispersion of nanomaterials in lubricating oil plays an important role in the lubrication and wear-resistance properties.In this work, supramolecular layered double hydroxides (LDHs) were prepared and added to lubricating oil with different dispersants.The content of key elements twist crimson crush in the samples was measured by an oil element analyzer, and the dispersion properties of different samples were studied.The friction coefficient of the samples was measured by high-frequency linear vibration (SRV), and the morphology and composition were characterized by SEM to study the antiwear performance and action mechanism of LDH.The oxidation induction time of the samples was measured by RBOT to study the antioxygenic properties of LDH in lubricating oil.

The results show that LDH can be well-dispersed in lubricating oil with the action of specific dispersants.After adding LDH, the 2018 nissan sentra windshield antiwear performance of lubricating oil was improved, as a uniform and dense protective film was formed on the friction surface.
