TL;DR: In this article, three methods of interpretation of contact angles in terms of surface tension of liquid and solid are correlated, and it is shown that the critical surface tension for wetting γ c is dependant in a specific way on the nature of the liquid system used regardless of the nature the solid.
Abstract: Three methods of interpretation of contact angles in terms of surface tension of liquid and solid are correlated. It is shown that the critical surface tension for wetting γ c is dependant in a specific way on the nature of the liquid system used regardless of the nature of the solid. Equations are derived which express the limiting values γ c may assume for a liquid/solid system. γ c is also correlated with the Good-Girifalco treatment of contact angles and experimentally determined values of the parameter φ are compared with theoretical calculations from molar volumes of normal alcohol-paraffin wax interfaces. The Fowkes method of contact angle interpretation is used to derive values for the polar and dispersion force components of liquid surface tensions for three alcohol/water solution series and two organic acid/water solutions.
