Effective Surface Driving Force Causing Liquid to Spread on Solid Surfaces

Abstract

Measurements of the dynamic and equilibrium contact angles of a sessile drop on solid surfaces has been used as a method to study wetting behaviour. When a small sessile drop spreads on a flat solid surface, the resultant of the surface forces can be conceived as the main driving force that causes spreading. The rate of wetting can be considered to be represented also by the increase in the liquid-solid interfacial contact area.
