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.
