The Polymer Reference Interaction Site Model (PRISM) theory is employed to investigate
structure, effective forces, and thermodynamics in dense polymer-particle mixtures in the
one and two particle limit. The influence of particle size, degree of polymerization, and
polymer reduced density is established. In the athermal limit, the surface excess is negative
implying an entropic dewetting interface. Polymer induced depletion interactions are
quantified via the particle-particle pair correlation function and potential of mean force. A …
