Flexible Piezoelectric Elastomer Formed by Optimal Crosslinking of Polyrotaxane |
| 초록 |
The main contribution of this research is to report the piezoelectric property of the mechanically interlocked molecular structure, called polyrotaxane (PRX) composed of ring-shaped alpha-cyclodextrins (CDs) threaded onto the linear poly(ethylene glycol) (PEG). PRX is a molecular necklace-like supermolecule that the threaded molecules are able to be dynamically slided and rotated. Therefore, PRX-based material has been mainly researched to provide slidable crosslinking sites into the networked polymers for developing a tough and stretchable polymer materials. In this research, we optimized the crosslinking state of the PRX to prepare the partially crystallized PRX elastomer. As a result, the non-crosslinked PRX area showed the rod-like anisotropic crystalline structure which is considered to be responsible for the piezoelectric property, and mechanically tough piezoelectric elastomer was prepared by the crosslinked PRX area. |
