On the bridge hypothesis in the glass transition of freestanding polymer films
Haggai Bonneau, Maxence Arutkin, Rainni Chen +3
Freestanding thin polymer films with high molecular weights exhibit an anomalous decrease in the glass-transition temperature with film thickness. Specifically, in such materials,…

Cooperative strings and glassy dynamics in various confined geometries
Maxence Arutkin, Elie Raphaël, James Forrest +1
Previously, we developed a minimal model based on random cooperative strings for the relaxation of supercooled liquids in the bulk and near free interfaces, and we recovered some k…

Using Mw dependence of surface dynamics of glassy polymers to probe the length scale of free surface mobility
Yu Chai, Thomas Salez, James Forrest
We describe a series of surface levelling experiments in glassy polystyrene (PS) of varying molecular weight. The evolution through a mobile surface layer is described by the glass…
