How to Choose among Neumann method, Fowkes Method, and Oss & Good method for Surface Free Energy Measurement?

These three methods are the most widely used methods to calculate the solid surface energy. Any of them can calculate the solid surface energy for you. However, the literature suggests that depending on the type of surface you want to do the measurement for, one/ two of these methods may perform better than others. So, we suggest that you first check what method is most widely used for your sample in the literature and select the same when you do your measurement.
