3.6 Tripathi, Dominik and Chapman
Tripathi and Chapman [60] developed interfacial SAFT (or iSAFT) as an extension
of the first version of the density functional theory of Segura et. al. [62] for associating
fluids to polyatomic fluids. The excess free energy functional due to the formation
of chains is derived along similar lines as SAFT. Considering the polyatomic system
as a mixture of associating atomic fluids in the limit of complete association, the
free energy functional can be derived from Wertheim’s TPTl. The derivation of the
theory (for chains of m segments as shown in the figure 3.2) is briefly discussed below.

The Helmholtz energy of a mixture of associating fluids can be written as
A∖pa] = Ai‰] + Aex^‰} + Aιsx'aaso‰] + AEX"att[pa],
where various contributions to the free energy functional are: Ald is the ideal gas free
