MXenes: A Model Material for Solid Lubricants

Two-dimensional materials with graphene-like structure have gained remarkable attention, because they have demonstrated remarkable tribological properties, even when applying only one or a few atomic layers of the material to the contact zone. However, the mechanisms of friction reduction and the influence of the materials’ structural and mechanical properties on the latter are still not well understood. MXenes, which are 2D transition metal carbides, nitrides, and carbonitrides, offer an extreme versatility in terms of composition, layer thickness, and surface terminations. This makes them ideal model materials to study the influence of theses parameters on tribological behaviour.
