    Extract. We consider a ternary mixture of hard colloidal spheres, ideal polymer spheres, and rigid vanishingly thin needles, which model stretched polymers or colloidal rods. For hard needle-polymer interactions, we predict rich phase diagrams, exhibiting three-phase coexistence, and reentrant demixing behavior. [more]

    Rod-sphere mixtures

    The DFT of [19] was extended to treat rod-rod interactions [30] [49], and used for free fluid interfaces [30] and wetting at a hard wall [40]. Simulations [42] confirmed unusual interfacial rod ordering. See [25] for the demixing phase behavior of the system upon adding polymers.
