Abstract. [Contribution to the proceedings of the conference "Mathematical
Results in Statistical Mechanics", Marseille July 2731 1998]
We review recent results about the macroscopic description of phase
separation in the 2D Ising model, with special emphasis on boundary
effects and related surface phase transitions. In particular, after
having recalled some facts about the wetting transition, we describe
two situations in which this transition has major consequences
at the macroscopic scale. We also briefly describe a more general
situation for which it is possible to derive the thermodynamical
variational problem characterizing the interfaces of the equilibrium
state.
