On the macroscale, adding fluorine atoms to carbon-based materials makes for water-repellant, non-stick surfaces, such as Teflon. However, on the nanoscale, adding fluorine to graphene had been reported to vastly increase the friction experienced when sliding against the material. Through a combination of physical experiments and atomistic simulations, scientists have discovered the mechanism behind this surprising finding, which could help researchers better design and control the surface properties of new materials.
