Electrochemically Tunable Photonic Gels with Bistability via Ionic Crosslinking |
| 초록 |
Responsive photonic crystals have been of great interest due to their potential applications in sensors, displays and optoelectronics. Recently our group developed photonic gels which are responsive to various chemical stimuli. Extending the work, we report electrically tunable photonic gels which exhibit bistability against applied electric signals. Electrically tunable photonic gels were prepared from self-assembly of polystyrene-b-poly(2-vinyl pyridine) (PS-b-P2VP) block copolymers. The position of photonic band gap (PBG) was tuned by controlling swelling/deswelling of P2VP layers via modulating the extent of ionic crosslinking with electrical signal. We anticipate that our photonic gels are applicable for full color electronic papers. |
