The GT was combined with two physically based equations of state (EoS), namely the perturbed-chain (PC) statistical associating fluid theory (SAFT) and its modification for polar substances PCP-SAFT. The GT applied to the planar phase interface was employed to predict the interfacial tension for various quadrupolar and dipolar substances and for binary mixtures including polar components. Besides the planar phase interface, the GT was also applied to the spherical phase interface simulating a critical cluster occurring in homogeneous nucleation of droplets. Application of the PCP-SAFT EoS provides a significant improvement compared to the PC-SAFT EoS, and it is clearly superior to the classical cubic Peng–Robinson EoS, which is still used for modeling droplet nucleation.
