Abstract
The interfacial tension of 10 polar liquids against hexane and tetradecane and the contact angle against paraffin, polyethylene, and polytetrafluoroethylene were measured. Work-of-adhesion values against any one nonpolar phase, calculated from these data, are independent of the polar liquid used. Values for the same polar liquid, however, differ with the nonpolar phase used. These differences are attributed to differing surface group densities and, hence, a different number of dispersion force interactions per unit area. These results explain the variations occurring in the Fowkes dispersion component of surface tension, γLd, for any liquid when it is determined using different nonpolar phases.
