Study on dispersibility and tribological behaviors of 2D ZnBDC MOFs as additive in oil.

Due to having the potential structure advantage in interfacial compatibility, the 2D MOFs nanosheets were worthy of being expected to improve the dispersion and stability of other 2D inorganic nanomaterials as additive in oil. In this work, the dispersion behavior of 2D ZnBDC nanosheets in oil was studied. Under two kinds of tribological modes (reciprocating ball-on-slider mode and ball-on-ball mode), for the first time we comprehensively studied the tribological behaviors of 2D MOFs based on ZnBDC (BDC = 1,4-benzene dicarboxylate) with the thickness of ca. 3.32 nm. Finally, we intensively investigated the effects of the adding content, load and friction speed to the tribological behavior. The results indicated that there was an evident difference in tribological behavior of 2D ZnBDC nanosheets in oil under two modes.
