Abstract

We perform coarse-grained simulations of model nanoparticles having a diameter on the order of 10 nm in an unentangled polymer matrix in the limit of low nanoparticle concentration to understand how the presence of nanoparticles alter the segmental mobility in the interfacial zone about these particles. The scale of the interfacial zone is found to be on the order of a few nms, regardless of the polymer-nanoparticle interaction strength, and the scale grows modestly upon progressive cooling.
