제목 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.
