  Recent developments in off-lattice self-consistent field theories for
inhomogeneous complex fluids are reviewed. Particular emphasis is given to the
treatment of intermolecular interactions and compressibility, to the role of
fluctuations, and to the discussion of the coarse-graining length which is
inherent to the theory. Valuable insight can be gained from the comparison of
self-consistent field calculations with Monte Carlo simulations. Finally, some
applications of the theory to orientational properties of polymers and
copolymers at interfaces, and to the phase behavior of amphiphiles at surfaces,
are presented.
