The periodic nanostructures in photonic crystals generate the photonic bandgap, resulting in the reflection of selected wavelengths. The structural colors from photonic crystals facilitate unique applications such as sensors or displays. However, a film format that is most common for photonic crystals has its limit from the absence of reconfigurability or flexibility. In this study, photonic tiles are fabricated and assembled at the air-water interface so that novel photonic surfaces can be achieved. We use colloidal particles to make non-close-packed and periodic pores in a polymer matrix. One side of each tile is physically etched to make the surface and side almost superhydrophobic by Cassie-Baxter model. The assembly makes a liquid photonic armor that protects underneath environment from certain wavelengths. The armor can also be transferred onto a solid substrate. Furthermore, a water marble surrounded by photonic tiles can be obtained after the gelation of the inner water. |
