Experimental analysis shows improved lubrication performance in castor oil with 2D Cu(2,6-NDC) nanosheets, indicating potential as a lubrication additive.
Key Points
The 0.08 wt % 2D Cu(2,6-NDC) in castor oil reduced the average friction coefficient by 42.7%.
Worn surface analysis revealed a synergistic lubrication mechanism in the nanosheet-enhanced castor oil.
The nanosheets demonstrated exceptional dispersion stability in castor oil for over 7 days, preventing sedimentation.
Tribological evaluation was conducted using a four-ball tester to assess lubrication performance against pure castor oil.
