Abstract

Results of wetting studied in two liquid systems on mixed monolayers of CH₃(CH₂)₁₁SH (DDT) and HO(CH₂)₁₁SH (HUT) on gold surfaces are reported. For the two liquid systems reported here, there appears to be a strong orthogonality between the cases of octane in water and water in octane. The observation of the shift of an apparent wetting transition is ascribed to the water concentration in the ambient. Thus, as the amount of water present in the ambient was decreased, the surface OH concentration at which the transition occurred was pushed to higher values. This is analogous to measurements made for HD in air, on these surfaces, where it was found that the position of the transition was affected by the relative humidity.
