Abstract

The thermodynamic and structural properties of ideal and repelling rigid rod-polymers were studied by using liquid-state integral equations. The function of the rod aspect ratio and sphere/rod size asymmetry was analyzed over a wide range of system parameters encompassing the colloid, nanoparticle and crossover regimes. The results showed that the liquid-state theory underestimates depletion attractions effects in the colloidal regime of short rods and large spheres due to nonlocal entropic repulsion effects between polymers and particles not captured by the classic Percus-Yevick approximations.
