Abstract
The interface issue of two‐dimensional (2D) nanomaterials has seriously restricted their applications in the past. To date, there have been few reports on the friction behavior of 2D MOFs. Herein, 2D Zn(Bim)(OAc) metal–organic framework structure nanosheets with a thickness of ca. 4 nm were successfully prepared via convenient ultrasonic‐assisted exfoliation in solvents. For the first time, we probed the dispersion performance of the as‐obtained 2D Zn(Bim)(OAc) in different oils, and intensively investigated the tribological behavior. The results indicated that the as‐obtained 2D Zn(Bim)(OAc) used as an additive showed the preferable friction reducing performance and wear resistance in liquid paraffin, and showed the better dispersivity in glycerol.
