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,…
Surface and Bulk Relaxation of Vapour-Deposited Polystyrene Glasses
Junjie Yin, Christian Pedersen, Michael Thees +3
We have studied the liquid-like response of the surface of vapour-deposited glassy films of polystyrene to the introduction of gold nanoparticles on the surface. The build-up of po…
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…
Controlling Marangoni induced instabilities in spin-cast polymer films: how to prepare uniform films
Paul D. Fowler, Celine Ruscher, Joshua D. McGraw +2
In both research and industrial settings spin coating is extensively used to prepare highly uniform thin polymer films. However, under certain conditions, spin coating results in f…
Cooperative strings in glassy nanoparticles
Maxence Arutkin, Elie Raphaël, James A. Forrest +1
Motivated by recent experimental results on glassy polymer nanoparticles, we develop a minimal theoretical framework for the glass transition in spherical confinement. This is acco…
Cooperative Strings and Glassy Interfaces
Thomas Salez, Justin Salez, Kari Dalnoki-Veress +2
We introduce a minimal theory of glass formation based on the ideas of molecular crowding and resultant string-like cooperative rearrangement, and address the effects of free inter…
A direct quantitative measure of surface mobility in a glassy polymer
Yu Chai, Thomas Salez, Joshua D. McGraw +4
Thin polymer films have striking dynamical properties that differ from their bulk counterparts. With the simple geometry of a stepped polymer film on a substrate, we probe mobility…
