Impact of Polymer Film
Thickness on Glass Transition and Chain Conformation
 |
|
The glass transition behavior and conformational
variations of polymer films are investigated
across bulk, confined, and free-standing states.
By spanning a wide range of film thicknesses,
this work captures how spatial confinement, free
surfaces, and entanglement densities modify
thermodynamic behaviors and chain conformation.

Glass Transition and Chain conformations in Thin Films: Systematic investigation of chain conformational change and the glass transition temperature Tg across bulk melts, confined films, and free-standing films. This work identifies how confinement and free surfaces impact thermal properties compared to bulk behavior, demonstrating that deviations are governed by the intrinsic properties of polymer melt systems.
