The continuum self-consistent field theory on mixtures of flexible polymers and small liquid crystalline molecules is developed. Small liquid ciystalline molecules are modeled as monomers with orientations independent of their positions and Maier-Saupe anisotropic interaction between small liquid ciystalline molecules is considered. For homogeneous case, the self-consistent field theory is reduced into Flory-Huggins solution theory and Maier-Saupe liquid crystal theory. The theory is applied to study the interfacial properties in mixtures of flexible polymers and small liquid crystalline molecules by solving the self-consistent field equation set numerically. The basic results are consistent with those obtained by Helfand lattice interface theory and lattice Monte Carlo simulation.
