| Research Abstract |
The present study investigated the physical basis of the deformation function in order to produce the soft active composites composed of the soft active materials with fibers. The glass transition characterizing the function of shape memory polymer of polyurethane series was first simulated using molecular simulations, while the relationship betweenthe functional degradation of shape memory polymer to its internal morphological change was clarified using fluorescence spectroscopy. The discussion of the functionality based on the change of free volume and molecular mobility was found to be effective.
