Effects of free-surface and interfacial layers and plasticizer content on the distribution of glass transition temperatures in nanoconfined polymers
Abstract
<p>A novel fluorescence/multilayer method has been developed allowing the first determination of the distribution of glass transition temperatures (Tg) in thin and ultrathin polymer films. The perturbation in polymer dynamics associated with Tg near a free surface of a polymer film, leading to a lower Tg at the surface, affects the local Tg several tens of nanometers into the film. The extent to which the Tg dynamics smoothly transition from enhanced to bulk states depends strongly on nanoconfinement. However, the impact of nanoconfinement on Tg is also a strong function of plasticizer content and attractive interactions at a polymer-substrate interface. The potential of these studies for understanding polymer nanocomposite behavior is discussed.</p>
