We report the structural relaxation process of irreversibly adsorbed polymer chains via
thermal annealing that lie flat on a solid (“flattened chains”). Amorphous polystyrene and …

Sum-frequency generation spectroscopy was employed to follow the conformation evolution
of polystyrene chains at the surface of a spin-coated film in a temperature-ramping mode as …

Thermal annealing is one of the most indispensable polymer fabrication processes and
plays essential roles in controlling morphologies and properties of polymeric materials. We …

By means of sum-frequency generation spectroscopy, we report a depth-resolved
measurement of the local conformation and chain relaxation of polystyrene (hPS) located at …

The local conformation of polymer chains in a film at a substrate interface was examined by
sum-frequency generation spectroscopy. When a polystyrene (PS) film was prepared on a …

Confined at the nanoscale level, polymers crystallize much slower than in bulk, and in some
cases, the formation of ordered structure is inhibited within extremely long experimental time …

We measured the local glass transition temperature T g (z) of polystyrene (PS) as a function
of distance z from a silica substrate with end-grafted chains using fluorescence, where …

The time scale that controls polymer chain relaxation has taken on a new importance as the
paradigm for polymer innovation evolves from three dimensions to two. 1 Nanotechnology …

Despite having very similar bulk properties such as glass-transition temperature (T g),
density, and fragility, polystyrene (PS) and poly (methyl methacrylate)(PMMA) exhibit …

Controlling polymer/substrate interfaces without modifying chemistry is nowadays possible
by finely tuning the formation of adsorbed layers. The complex processes leading to …
