A theoretical study was conducted to investigate the wetting behavior of liquid meniscus on a vertical plate with three-dimensional random characteristics of heterogeneity and roughness. The thermodynamic stable condition was derived by considering the minimum of system free energy. The local stable condition leads to a result similar to that obtained for a plate with two-dimensional characteristics, that is, the system has many meta-stable states. For the stable condition of the whole system, a relation was derived between the macroscopically observed contact angle and the surface characteristics. The product of cosine of the contact angle and liquid surface tension is equal to the energy difference for the liquid to wet the plate by apparent unit area. If the liquid wets the solid surface reversibly, there is only one contact angle observed macroscopically. This fact suggests that the contact angle hysteresis is caused by the irreversible motion when the liquid advances or recedes on the solid surface. The well-known Cassies and Wenzels contact angles are explained as those corresponding to a thermodynamically stable condition when the liquid wets the solid reversibly.

“…Polymers may provide the solid substrate, the spreading liquid, or both. Mason and coworkers [378][379][380][381] have described interesting theoretical and experimental results relating the effect of surface roughness to wetting. These authors have explored the concept of wettability theoretically [379], and they have described the equilibrium contact angle which a liquid surface makes with asolid it contacts as a measure of that wettability [380].…”

“…These authors have explored the concept of wettability theoretically [379], and they have described the equilibrium contact angle which a liquid surface makes with asolid it contacts as a measure of that wettability [380]. The SEM was used to demonstrate and confirm these theoretical projections [378,381]. In the early study [378], molten drops of PE and PMMA were allowed to spread and solidify on a paper substrate prior to standard preparation for SEM.…”

“…Later, poly(-phenyl ether) (PPE) vacuum pump oll (Santovac-5-Monsanto Chemicals), which is not volatile, was used for dynamic studies. The PPE was fed through a hole in the sampie stub, from outside the specimen chamber, and the wetting experiment was recorded on video tape [381]. Mori et al [382] used freshly cleaved mica surfaces as steps 60 nm in height to inhibit wetting.…”
