Deciphering mechanistic role of oxygen functional groups in graphene crumpled balls for high-temperature lubrication

Key Points

• Improved tribological performance supports the effectiveness of oxygen functional groups in lubrication systems.
• The incorporation of oxygen functional groups led to a notable decrease in friction coefficients during high-temperature tests.
• Analysis of graphene crumpled balls indicated superior properties in reducing wear compared to traditional lubricants.
• These findings may enable the development of advanced lubrication materials, though further research is needed.
