    Abstract:

    To explore the optical functional characteristics and bionic application potential of morpho menelaus wing scale, the responsive optical performance test and microstructure characterization were carried out, and the visual bionic model of wing scale was constructed. Furthermore, the mapping relationship between the multi-scale hierarchical micro/nano structure and the response functional characteristics in the visible and near infrared bands was revealed. The upper and lower scales of the wing have periodic fine structures, and the ridge structures are stacked into comb-like stack structure and tower-like grating structure by chitin lamellae, respectively. Rayleigh scattering, multilayer interference, photonic band gap and other optical effects make it with sensitive color changing response characteristics to the changes of external media filling and light incidence angle. Moreover, the reflectivity of near infrared band is adjustable. The unique optical properties of morpho menelaus wing scale can provide a new idea for the development of bionic stealth functional materials and components with adaptive color change and variable emissivity.
