Lecture 14: Gauging Surface Free Energy of Solids and Surface Processes

This lecture is the third and final of Chapter 5. Having introduced contact angle measurements in the previous lecture, we will apply such measurements to gauge polymeric solids' surface energy. We will review both one-component and two-component methods. Such values are useful for estimating the strength of adhesion, the extent of spreading, work of immersion, and other phenomenon involving the interactions between liquids and solids.
