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 …

Polymer coatings of nanometric thickness are about to enter in everyday life as part of a
wide range of applications such as protective layers, stimuli-responsive membranes or as …

It is generally believed that the strength of the polymer–nanoparticle interaction controls the
modification of near-interface segmental mobility in polymer nanocomposites (PNCs) …

The nature of alterations to dynamics and vitrification in the nanoscale vicinity of interfaces—
commonly referred to as “nanoconfinement” effects on the glass transition—has been an …

Polymers are increasingly being used in applications with nanostructured morphologies
where almost all polymer molecules are within a few tens to hundreds of nanometers from …

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

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 …

Two challenging scientific disciplines, ie, the physics of glasses [Anderson, Science 267,
1615 (1995); Kennedy and Norman, Science 309, 75 (2005)] and interface chemistry …

When cooled at constant rate, a 25 nm thin film of poly (4-tert-butylstyrene) vitrifies 50 K
lower than in bulk. This record sets the largest depression in thermal glass transition …

The properties of nanostructured polymeric materials reflect the presence of a dynamic
interphase in which polymer segmental dynamics, glass formation, mechanics, and transport …
