Intrinsically stretchable semiconducting polymer thin films with simultaneously enhanced crystallinity and ductility |
| 초록 |
Despite emerging scientific interest in polymer-based stretchable electronics, the trade-off between crystallinity and ductility of semiconducting polymers hinders the development of high-performance stretchable electronics. Here, we report a simultaneous enhancement of crystallinity and ductility of a benzotriazole-based polymer thin film enabled by reversible orientation of bimodal crystallites. The thin film shows bimodal crystalline structure with enhanced degree of crystallinity upon thermal annealing, and the annealed thin film yields improved charge carrier mobility (μ) of 0.2 cm2/V-s and crack onset strain (εc) of 100%, which are two orders of magnitude and two times higher than those of the as-prepared thin film (μ = 0.002 cm2/V-s; εc < 50%), respectively. Our results provide new insight into how crystalline structure affect μ and ductility of semiconducting polymer thin films and will facilitate the design of high-performance and stretchable semiconducting polymers. |
