Photonic Gels from Self Assembly of Block Copolymers: Tunability, Hysteresis and Fixation of Photonic Stop Bands |
| 초록 |
Smart gels have recently associated with photonic crystals to form photonic gels. Since these photonic gels are capable of reversibly converting the volume change of gels induced in response to external chemical or electric stimuli into characteristic optical signals, they have been considered not only as a good platform for label-free chemical or biological detection, actuators or optical switches but also as a good model system to investigate gel swelling behaviour. Herein, we report block copolymer photonic gels self-assembled from polystyrene-b-poly(2-vinyl pyridine) (PS-b-P2VP) block copolymers. We are going to demonstrate that selective swelling of lamellar structure allows extremely large tunability of the photonic stop band from UV region to IR region (λpeak=3501600 nm). Furthermore we will report on optical hysteric behaviour and its tunability in the photonic gels, and finally on fabrication of organic/inorganic hybrid photonic gels with frozen photonic stop bands. |
