Abstract

Recent observations using fluorophore probes of local dynamics in polymer films have provided new insight into the glass transition. Using a percolation model, we predict the local T g in a polymer film, as a function of distance from a substrate or a free surface. Our predictions are in good agreement with the observed elevation of T g near a substrate, whereas the observed reduction of T g near a free surface is too strong to be accounted for by percolation effects.
