The glass transition and kinetics in stacked polystyrene ultrathin films

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The kinetic behavior of stacked polystyrene ultrathin films is investigated by differential scanning calorimetry (DSC) and compared to the behavior of bulk polystyrene. The cooling rate dependence of the limiting fictive temperature, Tf' is found to be higher for the stacked thin film samples consistent with other results in the literature. We also find that the rate of physical aging of the stacked thin films is accelerated at the same aging temperature due to their depressed glass transition temperature values.
