Physical aging is a ubiquitous phenomenon in glassy materials and originates from the fact
that they are generally out-of-equilibrium. Due to the technological and fundamental …

We review the recent activity aiming to clarify glassy dynamics in nanostructured polymer
glasses, in particular thin films, nanocomposites and nanospheres. Special emphasis is …

We investigated the kinetics of enthalpy recovery of several glass-forming polymers at
temperatures significantly below the glass transition temperature (T g) and for aging times …

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 …

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 …

This work deals with effects of polymer molecular weight, W m, below the entanglement
threshold, W m, e, on molecular dynamics of polydimethylsiloxane (PDMS) adsorbed onto …

The nanoconfinement effects of glassy polymer thin films on their thermal and mechanical
properties have been investigated thoroughly, especially with an emphasis on its altered …

The adsorption of polymers on solid surfaces is common in many industrial applications,
such as coatings, paints, catalysis, colloids, and adhesion processes. The properties of …

We performed a systematic study on the recoverable enthalpy in several glass-forming
polymers. We found that after prolonged isothermal physical aging the enthalpy reaches a …

The physical aging of polystyrene (PS) free-standing films has been investigated as a
function of the films thickness, ranging from several micrometers to tens of nanometers. In …
