Spiral Photonic Actuators |
| 초록 |
Color-tunable spiral photonic actuators with both dimensional and optical functionalities that respond to environmental chemistry were constructed. When the transparent photonic actuator is swollen in hydrophilic acetic acid, right-handed spirals that exhibit angularly dependent colors from Bragg diffraction are formed. On the other hand, when the transparent photonic actuator is swollen in hydrophobic hexane solvent, a left-handed spiral actuator with an angularly independent bluish color is formed. After deswelling, all spiral photonic actuators returned back to the transparent planar state. These color-tunable, reversible spiral photonic switches can be useful as mechanical actuators and electrical devices as well as optical components. |
