The Helmholtz free energy functional for two-site associating Lennard-Jones (LJ) fluid confined in slit pores was established by combining the modified fundamental measure theory (MFMT) and first-order mean-spherical approximation theory (FMSA). The interfacial tension isotherms and the equili- brium interfacial tensions were investigated by using the density functional theory (DFT). The effects of the wall force, association energy and pore width on interfacial tensions were demonstrated.

Key words: two-site associating Lennard-Jones fluid, slit pore, interfacial tension, density functional theory
