AI Technical Summary
Technical Problem
Two-dimensional Co-BDC nanosheets are prone to agglomeration in lubricating oil, affecting their stability during friction.
Method used
By loading silver nanoparticles in a two-dimensional sheet-like cobalt-based organometallic frame, the van der Waals force between layers is weakened, the nanosheets are prevented from agglomeration, and the sliding friction is transformed into rolling friction during the friction process.
Benefits of technology
The good dispersion stability of the cobalt-based organometallic frame loaded with silver nanoparticles in the lubricating oil is achieved, the friction and wear between mechanical components is reduced, and the tribological performance is improved.
