Interfacial Self-Assembly of Amphiphilic Tiles for Reconfigurable Photonic Surfaces |
| 초록 |
Photonic crystals are periodic nanostructures where certain wavelengths cannot exist on the ground of photonic bandgap. Many organisms in nature have an array of photonic crystal structures at the epidermal cell for photo-protection or higher photosynthetic efficiency. Photonic surface formed at the air-water interface realizes as-mentioned environment as the epidermal photonic crystals work. Here, photonic tiles with nonclose-packed array of cavities are physically and chemically treated so that resulting amphiphilicity facilitates the assembly of the tiles at the air-water interface. The assembly is enhanced in that the attractive force between tiles at the interface increases by modification and the tiles are hardly tilted or immersed in water. Their assembly produces reconfigurable photonic surface in two- and three-dimensional space. The assembly of photonic tiles on water can also be transferred onto a elastomer or hard substrate, which is a new way of photonic surface coating. |
