θ = contact angle; = liquid’s total surface tension; and = apolar Lifshitz—van der Waals components of the liquid and the solid γlv- and = Lewis acid-base contributions of either the solid or the liquid phase; = electron donor (Lewis base) and = electron acceptor (Lewis acid) components; “lv” and “sv” = denote the interfacial liquid-vapor and surface-vapor tensions; “p” and “d” = denote the polar and disperse components of total surface tension, ; = polar Lewis acid-base interaction.
