Another advantage is that these “thermo-hydrodynamic” approaches make it easier to bridge the gap between the smallest scales, where microfilms possibly exist, and larger scales, where apparent contact angles are determined, as also seen in this chapter. , 2008). We rather consider complete or partial wetting situations where the typical slope the liquid/gas interface makes with the substrate is not too large, such that the lubrication assumption may be Precursor Films and Contact Line Microstructures 33 used.

Soc. Lond. 95, 65. Chapter 2 CONTACT ANGLES AND THE SURFACE FREE ENERGY OF SOLIDS Odile Carrier and Daniel Bonn Institute of Physics, University of Amsterdam, Amsterdam, The Netherlands This section presents the contact angle, its determination, hysteresis, and the different approaches to correct it, depending on the substrate roughness. 1 Equilibrium contact angle: Zisman plots As presented in Chapter 1, the cosine of the equilibrium contact angle θ is linked to the three surface tensions according to the Young equation (1805) for pure liquids on an ideal solid substrate (smooth and homogeneous): σsv 5 σsl 1 σlv cos θ ð2:1Þ The contact angle is then used to characterize the wetting properties of solids: a droplet is deposited on the substrate, and the equilibrium contact angle is measured.
