Characterizing the total surface energy profile of a solid is a useful tool for comparing the performance of similar materials. It also provides a good starting point for estimating numerous other physicochemical properties such as aggregation likelihood, flowability, etc. However, it is important to distinguish between the different contributions to the total surface energy of a solid, namely the dispersive and specific components.
Assessment of a surface’s specific energy indicates its polarity and its tendency to interact with polar solvents and charged bodies. Key physiochemical properties such as wettability can be estimated using this measure. Further study can determine if a surface displays more acid or basic character which can be vital in determining a material’s functionality.
