TL;DR: In this article, the surface tension of a liquid can be split into polar and dispersive components, and these same components can be obtained for a solid surface by the measurement of contact angles.

TL;DR: In this paper, contact angle measurements of five n-alkanes, dodecane through hexadecane, on Teflon (FEP) were obtained as a function of drop size.
Abstract: We report contact angle measurements of five n-alkanes, dodecane through hexadecane, on Teflon (FEP) as a function of drop size. In all cases the contact angles decreased by approximately 5° when the drop size was increased from approximately 1 to 4 mm contact radius. A complete solution to the problem of mechanical equilibrium of a sessile drop on a solid surface indicates that the dependence of the contact angle on drop size may be explained by including the effect of line tension in the Young equation. The observed drop size dependence of the contact angle yields a line tension of (2.5 ± 0.5) × 10−6 J/m. Over the range of n-alkanes studied it was not possible to discern any dependence of the line tension on liquid surface tension.
