Differential Coupling of Nanoparticle Translational and Rotational Diffusion to Polymer Relaxation Modes in Unentangled Polymer Melts

Abstract The diffusion of spherical nanoparticles (NPs) in unentangled polymer melts is investigated using coarse-grained molecular dynamics simulations. We show that for both translational and rotational diffusion, when the NP diameter d is smaller than a characteristic length l...
