In previous reports, covalent organic frameworks (COFs) have demonstrated significant potential as lubricant additives. Herein, we embedded Ag nanoparticles in the DT-COF (polycondensation polymer of 2,5-dihydroxyterephthalaldehyde and 4,4′,4″-(1,3,5-triazine-2,4,6-triyl) trianiline) matrix via ball milling method utilized this composite (Ag@DT-COF) an additive for supermolecule oil gel. The low molecular weight gelator effectively mitigates dispersion challenges COFs oil, while enhance repairing effect antipressure performance lubricant. resulting Ag@DT-COF gel exhibits a reduction average friction coefficient wear volume base by 46.0% 87.5%, respectively, increases load-carrying capacity to 750 N. remarkable tribological properties are attributed easy adsorption DT-COF, antiwear characteristic nanoparticles, that ensures long-term stability

The development of advanced lubricant additives is crucial for improving the tribological properties in mechanical systems. Doping has been certified as one effective methods enhancing lubricating carbon nanomaterials. Herein, multielement (B, N, P)-doped porous nanosheets P@PCNs) were successfully prepared using ionic liquid-assisted pyrolysis "copper–pyridine" coordination metal–organic frameworks (Cu-MOFs). as-obtained B, P@PCNs exhibit good friction-reducing and antiwear behavior additives. Compared to base oil 500SN, friction coefficient was reduced 0.104, resulting a 77.5% decrease wear volume, load-bearing capacity increased from 150 550 N simultaneously. Through Raman XPS analysis, it ascertained that boron, nitrogen, phosphorus elements actively participate chemical reactions, formation protective film, which significantly mitigates tear pair by combining adsorption, restoration, polishing mechanisms.
