title: Nanometer-nanosecond oscillatory expansion and contraction behavior of polymer films induced by 248 nm excimer laser excitation.
abstract: Microregional mechanical measurements of a poly[methylmethacrylate) film can be made by a combined probe/measurement laser system, as represented in the picture. The localized nature of the laser systems allow quantification of the degree of expansion and contraction processes, as well as the glass-rubber transition. Such nondestructive techniques lead to the elucidation of polymer morphological dynamics.
