| 논문초록 | Structural Colors(SCs) of photonic crystals(PCs) based on self-assembly of colloids and block copolymers(BCPs) have been extensively studied with regards their potential in use of large area, low power reflective mode displays and stimuli-sensitive sensors. Here, we demonstrate an ink-jet printable and re-writable BCP SC display that can be quickly written and erased over 50 times with resolution equivalent to that obtained with a commercial office ink jet printer. The writing process employs an easily modified printer for position and concentration controlled deposition of a water base ink containing a reversible cross-linking agent. The information can be readily erased and the system reset by application of hydrogen bromide. We also demonstrate that BCP SC is used as a highly stretchable, large strain capacitive sensor which can visualize the strain. Our BCP SC strain sensor exhibits fast strain response with multi-cycle reliability over 1000 times in both capacitance and SC change. |
