Certainly, the three vapour phase methods are the most fundamentally reliable; however, the use of surface energies derived from contact angles can be easier to work with in terms of trying to calculate the cohesive and adhesive natures of the surface under study. Our favoured approach at ...

It then considers how the surface tension, or surface free energy, of a liquid can be split into polar and dispersive components, and how these same components can be obtained for a solid surface by the measurement of contact angles. The final step in the argument is the derivation of ...

Macroscopic contact angles and contact angle hysteresis energy serve as one characterization of the surfaces. Measurement of contact line structure to micron resolution over centimeter lengths serves as another characterization. We also examine the dynamics of jumps along the contact line in the different...
Thus the formamide) was deposited on the sample surface and IGC data describe only a small (but highly significant) immediately, images of the drop in contact with the surface population of the surface, whereas the contact angle data were taken. The contact angles were generated automat- ...

On respreading, the absorbed water still present in the film allows instantaneous rewetting of the prewetted area, and contact angles match the receding values. By contrast, a nonabsorbent surface will register a contact angle on respreading that is close to the advancing angle, enabling one to...
