Abstract
Having introduced the concept of surface tension and free surface energy we will now turn to methods which allow us to determine these characteristic values. As it turns out, there are several straightforward methods which allow measuring the surface tension of a liquid conveniently. However, measuring the free energy of a surface is inherently more difficult because it is not a property directly accessible to measurement. In most cases, free energies of surfaces are measured via the characteristic contact angles that certain liquids will show on these surfaces. There are several theoretical models and measurement techniques derived thereof that allow determining the free surface energy. In this section, we will study the most relevant techniques.
