Abstract

In the out-of-equilibrium state above the volume phase transition temperature, poly(N-isopropyl acrylamide) hydrogels deswell non-diffusively, relaxing instead by a hyperdiffusive mechanism as in jammed systems. X-ray photon correlation spectroscopy is employed to show that the unconventional relaxation properties (linear dependence of the intensity correlation function both on time and on transfer wave vector) are the consequence of uniform deswelling.
