θ = contact angle; γsvTOT = liquid’s total surface tension; γlvLW and γsvLW = apolar Lifshitz—van der Waals components of the liquid and the solid γsv+γlvγlv- and γsvγlv+ = Lewis acid-base contributions of either the solid or the liquid phase; γsv= electron donor (Lewis base) and γsv+ = 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, γlvTOT;γsvAB = polar Lewis acid-base interaction.
