Flexible 1D photonic crystal multilayer films for humidity sensor and anti-counterfeiting film. |
| 초록 |
We studied a facile and practical polymeric 1D PC multilayer films for real-time monitoring humidity sensor with remarkable color change, sensitivity and reversibility. High and low refractive index polymer were synthesized by free radical polymerization with 1-10mol% of photo-crosslinkable monomer. We were prepared four different low refractive index polymer with different quaternization degree for controlled hydrophilicity. Polymeric 1D photonic crystal multilayer films were fabricated by alternating Low/High refractive index polymers with a simple spin coating. When relative humidity(RH) from 10% to 90%, the color of films rapidly change from violet to red and return to the original state instantly after exposure to air. In case of low degree of quaternization films can be applied as anti-counterfeiting films and high degree of quaternization films can be applied humidity sensor. |
