Structural fluctuations in cross-linked matrices with narrow pore size distribution

The interplay between water and hydrophilic polymer matrices is object of study in many papers. Incoherent elastic, quasielastic neutron scattering and NMR low resolution relaxometry are among the most informative approaches for the understanding of the behaviour of water in confining media. A problem often occurring in these studies is the structural heterogeneity of systems such as hydrogels. As a consequence, all the investigated features are smeared in their values and the analysis of the related distributions is not an easy task to match. For this reasons, we present here an incoherent elastic neutron scattering study of hydrated polymer matrices with a narrow distribution of the pore size.
