Query: Wetting behavior of a colloidal particle trapped at a composite
  liquid-vapor interface of a binary liquid mixture   A partially miscible binary liquid mixture, composed of A and B particles, is
considered theoretically under conditions for which a stable A-rich liquid
phase is in thermal equilibrium with the vapor phase. The B-rich liquid is
metastable. The liquids and the thermodynamic conditions are chosen such, that
the interface between the A-rich liquid and the vapor contains an intervening
wetting film of the B-rich phase. In order to obtain information about the
large-scale fluid structure around a colloidal particle, which is trapped at
such a composite liquid-vapor interface, three related and linked wetting
phenomena at planar liquid-vapor, wall-liquid, and wall-vapor interfaces are
studied analytically, using classical density functional theory in conjunction
with the sharp-kink approximation for the number density profiles of the A and
B particles. If in accordance with the so-called mixing rule the strength of
the A-B interaction is given by the geometric mean of the strengths of the A-A
and B-B interactions, and similarly the ratio between the wall-A and the wall-B
interaction, the scenario, in which the colloid is enclosed by a film of the
B-rich liquid, can be excluded. Up to six distinct wetting scenarios are
possible, if the above mixing rules for the fluid-wall and for the fluid-fluid
interactions are relaxed. The way the space of system parameters is divided
into domains corresponding to the six scenarios, and which of the domains
actually appear, depends on the signs of the deviations from the mixing rule
prescriptions. Relevant domains emerge, if the ratio between the strengths of
the wall-A and the wall-B interactions is reduced as compared to the mixing
rule prescription, or if the strength of the A-B interaction is increased to
values above the one from the mixing rule prescription. The range, within which
the contact angle may vary inside the various domains, is also studied.
