Response to 'Comment on 'Water-driven programmable polyurethane shape memory polymer: Demonstration and mechanism [Appl. Phys. Lett. 97, 056101 (2010)]''

摘要

Although the chemoresponsive feature has been demonstrated in a few types of shape memory polymers (SMPs) (e.g., in Refs. 1 and 2)," our understanding of the underline mechanism for triggering their shape recovery is still largely qualitatively. As such, the framework proposed in Ref. 4, despite of rather preliminary, could be a good initial step toward a more precise scheme for quantitative simulation in future. From this point of view, this piece of work is plausible. It is noticed that die derivation of the proposed framework in Ref. 4 starts from the thermodynamics of polymer solution, and the polymer refers to a particular SMP as a whole.
