Glass transition of polymers in bulk, confined geometries, and near interfaces

S Napolitano, E Glynos, NB Tito - Reports on Progress in Physics, 2017 - iopscience.iop.org
When cooled or pressurized, polymer melts exhibit a tremendous reduction in molecular
mobility. If the process is performed at a constant rate, the structural relaxation time of the …

Instability, self-organization and pattern formation in thin soft films

R Mukherjee, A Sharma - Soft matter, 2015 - pubs.rsc.org
The free surface of a thin soft polymer film is often found to become unstable and self-
organizes into various meso-scale structures. In this article we classify the instability of a thin …

Effect of nanostructure on the thermal glass transition and physical aging in polymer materials

D Cangialosi, A Alegria, J Colmenero - Progress in Polymer Science, 2016 - Elsevier

The calorimetric glass transition (T g) is measured for single polystyrene ultrathin films using
a commercial rapid-scanning chip calorimeter as a function of cooling rate and film …

Dynamics and thermodynamics of polymer glasses

D Cangialosi - Journal of Physics: Condensed Matter, 2014 - iopscience.iop.org
The fate of matter when decreasing the temperature at constant pressure is that of passing
from gas to liquid and, subsequently, from liquid to crystal. However, a class of materials can …
