Practical Contact Angle Measurement (5)

Custom-made models: from contact angle to surface free energy

The determination of the surface free energy (SFE) of a solid is the ultimate in contact angle measuring techniques. The method provides the user with important information about the material surface, such as its wettability and adhesiveness. In order to plan a measurement and draw the correct conclusions from the results a good knowledge of the scientific models upon which these are based is useful.

In this final part of our series on contact angle measurement the most important models for determining the SFE are described; these are used in practice (and in KRÜSS software).  In addition to the proper use of the models, it is also concerned with the practical aspects of SFE determination: selection of suitable test liquids, suitable ambient conditions and the consequences arising from the properties of the solid surface.
