The wetting of a surface by a liquid is discussed, including factors that influence the wetting action, and the measurement of surface tension.
The wetting of surfaces by liquids, which includes adhesives, can be understood by considering a droplet of liquid resting on a surface. The wetting action can be quantified using the various tensions that act at the point where the three phases, of liquid, solid and vapour, meet, as shown below. The tensions, or surface tensions, are represented by the symbol γ, and the subscripts L, S and V stand for liquid, solid and vapour. The surface tensions can be combined with the equilibrium contact angle, γ LV cos θ The surface tension, or surface free energy, γ, of a material can thus be…
