Superlubricity under ultrahigh contact pressure enabled by partially oxidized black phosphorus nanosheets

Abstract Superlubricity has recently raised an increasing interest owing to its great potential in energy saving and environmental benefits. Yet how to obtain stable superlubricity under an ultrahigh contact pressure (>1 GPa) still remains a challenge. Here, we demonstrate that robust liquid supe...
