ABSTRACT

Thus, the driving force for the reverse process is much less than for the wetting process. Consequently a simple drying of the wetted sample does not cause a significant hydrophobic recovery of the surface. From the viewpoint of interaction forces, the repulsive force between fluorine atoms and water molecules is not replaced by the attractive force in the similar magnitude, but the repulsive force is merely removed. The reverse process, therefore, may be more appropriately considered as a redistribution process of certain chemical moieties, which is driven by the local differential chemical potential of each species.
