摘要: We have developed a statistical-mechanical theory for the interfacial properties of molecular fluids characterized by strongly anisotropic pairwise potentials. The theory, which is generalization to mean-field (or van der Waals) Helmholtz free energy non-uniform spherical molecules, was applied nematic-isotropic and nematic-vapour interfaces simple model nematic liquid crystal. Our exhibits three fluid phases—a nematic, an isotropic vapour—which can co-exist in pairs, also simultaneously at low temperature triple point, T tr. present explicit results global phase diagram are good qualitative agreement with data on real crystals. studied detail various occurring different regions diagram. numerical calculations density orientational order parameter profiles nematic-isotrop...
