Abstract
THE interfacial tensions between a solid surface (S), a liquid (L) and its vapour (V) can be related as follows1: 
where the interaction parameter ϕ is virtually unity for intermolecular forces of dispersion type but rather less than unity for immiscible phases in general. When combined with Young's equation2: 
the result is: 
While this is broadly in accordance with Zisman's well-established empirical relationship3 for low-energy substrates, it fails to account for its rectilinear form.
