摘要：
The two-dimensional Ti3C2(OH)(2) nanosheets were synthesized by exfoliation of laminated Ti3AlC2 in HF and characterized by X-ray diffractometry, SEM, TEM, and HRTEM. The results indicated that the Ti3C2(OH)(2) compounds had 2D layer-like structures with a thickness of 10-20 nm, and the fabrication process of Ti3C2(OH)(2) nanosheets was discussed on the basis of the experimental facts. The tribological properties of Ti3C2(OH)(2) nanosheets as additives in base oil were investigated using a UMT-2 ball-ondisc tribotester. Under the determinate conditions, the friction coefficient of the base oil containing Ti3C2(OH)(2) nanosheets was lower than that of the base oil under 15 N load with 200 rpm, and decreased with increasing mass fraction of Ti3C2(OH)(2) nanosheets when it was < 1.0 wt%. A combination of sliding friction, and stable tribofilm on the rubbing surface could explain the improved tribological properties of Ti3C2(OH)(2) nanosheets as additives.
