Non-simple flow behavior in a polar van der Waals liquid: structural relaxation under scope
Silvia Arrese-Igor, Angel Alegria, Juan Colmenero
The non-exponential character of the structural relaxation is considered one of the hallmarks of the glassy dynamics and in this context, the singular shape observed by dielectric…
Insights into the Non-exponential Behaviour of the Dielectric Debye-like Relaxation in Monoalcohols
Silvia Arrese-Igor, Angel Alegría, Arantxa Arbe +1
More than 100 years after Debye proposed his model for the dielectric relaxation of monoalcohols (MA), some fundamental questions about their dynamics and its relation with the sup…
Effect of Chain Stiffness on the Structure of Single-Chain Polymer Nanoparticles
Angel J. Moreno, Petra Bacova, Federica Lo Verso +3
Polymeric single-chain nanoparticles (SCNPs) are soft nano-objects synthesized by purely intramolecular cross-linking of single polymer chains. By means of computer simulations, we…
Reaching the ideal glass transition by aging polymer films
Virginie M. Boucher, Daniele Cangialosi, Angel Alegria +1
Searching for the ideal glass transition, we exploit the ability of glassy polymer films to explore low energy states in remarkably short time scales. We use 30 nm thick polystyren…
Tunable Slow Dynamics in a New Class of Soft Colloids
Federica Lo Verso, Jose A. Pomposo, Juan Colmenero +1
By means of extensive simulations, we investigate concentrated solutions of globular single-chain nanoparticles (SCNPs), an emergent class of synthetic soft nano-objects. By increa…
Anomalous Molecular Weight Dependence of Chain Dynamics in Unentangled Polymer Blends with Strong Dynamic Asymmetry
Silvia Arrese-Igor, Angel Alegria, Angel J. Moreno +1
We address the general question of how the molecular weight dependence of chain dynamics in unentangled polymers is modified by blending. By dielectric spectroscopy we measure the…
