Descripción
Supramolecular polymer networks differ from their chemically crosslinked counterparts by the fact that the intermolecular bonds between associating groups can be created and destroyed reversibly, and this has a very strong effect on the dynamical properties and relaxation response of these materials. A detailed understanding of the effect that the association and dissociation kinetics of the reversible junctions have on the self-diffusion of associating networks is still missing, and it is important in order to predict and understand the mechanical properties, stability and self-healing capabilities of these type of soft materials. In a recent series of publications [1-2], the diffusion of linear and star polymers with associating groups was studied by means of forced Rayleigh scattering, showing an unexpected superdiffusive behaviour over a wide range of time and length scales. In this talk, we explain the origin of the observed superdiffusive behaviour, by means of scaling arguments, analytical theory and simulations.
