Abstract

Interfacial water layers attract more and more attention in both material sciences and life sciences because of two characteristics that depend on the polarity of the surfaces involved: crystalline order and surface stability. Their interplay allows us to understand friction at the nanoscale under realistic conditions, including but not limited to the extremely low friction between hydrogenated diamond species, the enhanced flow in carbon nanotubes, or the functionality of elastin fibers. The prospect that the low friction coefficients both in artificial systems and nature are due to the action of interfacial water layers is challenging and deserves study. Here we probed the bonding stability of water molecules on hydrogenated and non-hydrogenated diamond surfaces and found that the interfacial water layer masking hydrogenated diamond presents an exceptional stability, thereby explaining its direct involvement in lubrication.
