“Molecular view on polymers adsorbed on nanoparticle surfaces“
Abstract:
The outstanding performance of modern elastomers is dominated by the reinforcement arising from nanometric fillers. The compounds’ peculiar thermo-mechanical properties cannot be explained without consideration of an interphase, i.e., a region of polymer with modified properties. Previous results support a consensus picture of adsorbed components with locally increased Tg and gradient zone of a few nm. This talk focuses on more recent results, mostly obtained by proton low-resolution NMR as a probe of the segmental dynamics, that challenge the generality of this picture. […]
