Length-modulated Nitrene Induced Photo-crosslinking Networks in near-Amorphous Conjugated Polymer for Stretchable Electronics |
| 초록 |
Crosslinking of conjugated polymer films is an effective method to improve their ductile characteristics for the stretchable electronics. Although the structural design of crosslinkers has a significant influence on the microstructure and ductility of the crosslinked films, this has not yet been thoroughly investigated. We show how a molecular structure of crosslinkers affects the microstructure and deformability of crosslinked conjugated polymer films, and how crystallinity of conjugated polymers determines the underlying mechanism of mechanical improvements. A series of azide (N3)-based crosslinkers containing four different lengths of ethylene glycol units were synthesized. We found that the shortest azide crosslinker with an ethylene glycol monomer leads to the best improvement in the mechanical properties of crosslinked polymer films, due to the miscibility of the crosslinker. Systematic studies with various microstructural analysis suggest a new mechanical improvement mechanism. |
