In this article, the effects of size and confinement at the nanometre size scale on both the
melting temperature, T m, and the glass transition temperature, T g, are reviewed. Although …

In this article, we present a detailed account of important recent developments in the rapidly
evolving area of glass transitions in thin polymer films. We review the case of polymer films …

The elastic moduli of ultrathin poly (styrene)(PS) and poly (methylmethacrylate)(PMMA) films
of thickness ranging from 200 nm to 5 nm were investigated using a buckling-based …

The glass transition temperature T g and the temperature T α corresponding to the peak in
the dielectric loss due to the α process have been simultaneously determined as functions of …

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 …

Freely standing polystyrene films show an anomalous drop of the glass temperature when
the molecular weight is high and the thickness smaller than the coil size R 0. We present …

We review recent work on the motion of polymer molecules confined to thin films. There has
been considerable experimental evidence for large reductions in the glass transition …

We have used Brillouin light scattering to make a detailed study of the behavior of the glass
transition temperature T g in ultrathin, free-standing polystyrene films. The glass transitions …
