Structure and swelling of polymer networks: insights from NMR.
Kautsch. Gummi Kunstst. (KGK) 66, 52-58 (2013).
Recent advances in the microscopic understanding
of the mechanical properties
of model nanocomposites - polyethylacrylate
filled with monodispersed
spherical silica nanoparticles - are reviewed.
The structure of the fillers dispersion
has been obtained by small angle
neutron scattering combined with reverse
Monte Carlo simulations, yielding the
nanoparticles pair correlation function.
The dynamics of the polymer chains has
been investigated using low-field NMR.
It was interpreted using a glass transition
temperature gradient around the fillers.
The mechanical properties have been
studied using oscillatory shear experiments.
The Payne effect has been
found to be correlated with the average
number of immobilized polymer bridges
