Abstract

The friction and adhesion between a fluorocarbon monolayer-coated surface (FC) against a hydrocarbon monolayer-coated surface (HC) has been directly measured. The friction was found to be lower than the friction between a hydrocarbon monolayer against a hydrocarbon monolayer and a fluorocarbon monolayer against a fluorocarbon monolayer. No stick slip sliding was observed for speeds 0.8 m/s to 2.6 m/s. The fluorocarbon/hydrocarbon interface was adhesive, with the energy of interaction measured to be 14.9 mJ/m2 1.0 mJ/m2. As predicted from theory, the magnitude of the adhesion of a fluorocarbon monolayer against a hydrocarbon monolayer is between that measured for a fluorocarbon monolayer against a fluorocarbon monolayer and a hydrocarbon monolayer against a hydrocarbon monolayer. One may note that the interfacial energy, g, follows the general trend gFC/FC < gHC/FC < gHC/HC, whereas the shear stress, t, varies according to tFC/HC < tHC/HC < tFC/FC.
