The glass transition temperature (T g) of polymer thin films, one of the most important parameters to characterize the relaxation behavior of polymer chains in a thin film, has been …
Polymer properties, such as their mechanical strength, barrier properties, and dielectric response, can be dramatically improved by the addition of nanoparticles. This improvement …
We investigate the segmental dynamics and glass transition temperature (Tg) of polystyrene (PS) thin films. The former is investigated by alternating current (AC) calorimetry and …
Understanding why the glass transition temperature (T g) of polymers deviates substantially from the bulk with nanoscale confinement has been a 20-year mystery. Ever since the …
J Moll, SK Kumar - Macromolecules, 2012 - ACS Publications
The influence of geometric confinement on the glass transition temperature (Tg) of small molecules and high polymers has been thoroughly investigated in recent years. Starting with …
High purity cyclic PS (c-PS) samples with number-average molecular weight (MW) of 3.4 and 9.1 kg/mol were synthesized via atom transfer radical polymerization and “click” …

We use fluorescence from dye-labelled polymer to measure the glass transition temperatures (Tgs) across single-layer films and near surfaces and silica interfaces in …
We have performed molecular dynamics simulations to explore the influence of confinement on the glass-transition temperature T g for supported atactic-polystyrene (aPS) thin films of …
F Kremer, M Tress, EU Mapesa - Journal of Non-Crystalline Solids, 2015 - Elsevier
The long lasting highly controversial discussion on glassy dynamics and the glass transition temperature of polymers in nanometric layers and films seems to be converging based on a …
