Theoretical Foundation of Zisman's Empirical Equation for Wetting of Liquids on Solid Surfaces
Zhu, Ruzeng; Cui, Shuwen; Wang, Xiaosong
European Journal of Physics, v31 n2 p251-256 Mar 2010
Theories of wetting of liquids on solid surfaces under the condition that van der Waals force is dominant are briefly reviewed. We show theoretically that Zisman's empirical equation for wetting of liquids on solid surfaces is a linear approximation of the Young-van der Waals equation in the wetting region, and we express the two parameters in Zisman's empirical equation in terms of the dielectric polarizabilities of the solid and liquids. The materials contained in this paper are suitable for physics teaching of wetting phenomena for undergraduate, graduate, general physicist, etc. (Contains 1 figure.)
