Abstract

In this work, the modulus of polymer thin films for a homologous series of poly(n-alkyl methacrylate)s will be discussed. In particular, the impact of the degree of undercooling from bulk Tg on the deviations will be explored as Tg is significantly impacted by alkyl chain length. Bohme and de Pablo predicted that the modulus of nanoconfined polymers decrease even at temperatures well below Tg. Additionally as Tg is approached, the size scale at which the decreased modulus occurs increases. This work will experimentally examine these predictions.
