Single molecules reorientation reveals the dynamics of polymer glasses surface.

Abstract

The polymer glass surface can be many orders of magnitude more mobile than the interior. We probe dynamics with reorientation of single dye molecules spin-coated onto polymer films. Rotation jumps in transition dipole orientation are observed for approximately 30% of all single molecules. It is found for the first time that there are mainly three typical… (More)
