Mie Backscattering-Based Coloration of Randomly Distributed Stimuli-Responsible Polymer Particles |
| 초록 |
The coloration of randomly distributed polymer particles is investigated. It is observed that dilute dispersion of polymer particles displays colors because of the increased transport mean free path (l*) of scattered light which reduces the scattering number of Mie forward scattering and helps the revelation of colors from Mie backscattering. While selective extraction of Mie backscattering-based color at higher particle concentration is also carried out by adding a light absorber. Due to the difference in the distance of the scattering propagation path, Mie forward scattering is absorbed to the light absorber (carbon black, CB) more intensely and Mie backscattering-based color is revealed. Finally, stimuli-responsive particles that could change their size in specific conditions such as pH changes or exposure to heavy metal ions are prepared and the size-dependent color changes under the external stimuli are examined. |
