Phys. Rev. Lett. 101, 075702 (2008) [4 pages]Relation between Glass Transition Temperatures in Polymer Nanocomposites and Polymer Thin FilmsReceived 5 May 2008; published 14 August 2008 Motivated by recent experiments, we examine within a percolation model whether there is a quantitative equivalence in the glass transition temperatures of polymer thin films and polymer nanocomposites. Our results indicate that, while the qualitative behaviors of these systems are similar, a quantitative equivalence cannot be established in general. However, we propose a phenomenological scaling collapse of our results which suggests a simple framework by which the results of the thin films may be used to quantitatively predict the properties of polymer nanocomposites. © 2008 The American Physical Society URL:
