Abstract

The absolute heat capacity and the glass transition are measured for stacked polystyrene thin films using the step scan differential scanning calorimetric (DSC) method. We find that the absolute heat capacity in both the glass and liquid states decreases with decreasing film thickness and that the T g also decreases with decreasing film thickness. The results indicate that an understanding of T g at the nanoscale is elusive.
