Abstract

Description

Using X- ray photon correlation spectroscopy measurements on gold nanoparticles embedded in polymethylmethacrylate we provide evidence for existence of an intrinsic length scale for dynamic heterogeneity in polymer nanocomposites similar to that in other soft materials.We also show how the dynamics varies in a complex way with various parameters.
