Interface and chain confinement effects on the glass transition temperature of thin polymer films
Abstract
We have used Brillouin light scattering and ellipsometry to measure the glass transition temperature Tg of thin polystyrene (PS) films as a function of the film thickness h for two different molecular weights Mw. Three different film geometries were studied: freely standing films, films supported on a SiOx surface with the other film surface free (uncapped supported), and films supported on a SiOx surface and covered with a SiOx layer (capped …
