Classical Density Functional Theory (DFT) has shown to be a consistent framework for the study of surface thermodynamics, being used for the calculation of interfacial tensions and adsorption, to the calculation of properties of colloidal systems and self-assembly [1,2]. Classical DFT finds the local density profile of an inhomogeneous fluid system in the presence of fluid-fluid interfaces or fluid-solid surfaces, that later can be used for the calculation of interfacial tensions between fluid phases, or adsorption of fluids on the walls of an adsorbent.
