Morpho蝴蝶翅膀(MBW)的独特的层次显微结构表现出与角度无关的蓝色虹彩。生物模拟这些微结构并将其转化为功能性光子晶体(PhCs)吸引了科学家,但仍然具有挑战性。在这里,一个光可调的PhC是通过沉积含偶氮苯的线性液晶聚合物(LLCP)上的MBW模板。由于LLCP优异的机械性能和可变形性,所产生的3D双层微结构在UV光照射下表现出分层变形,导致反射峰(70 nm)蓝移和反射率的显著变化(40%)。这种可光调谐的PhC可能在颜料、化妆品和传感器中具有潜在的应用。
The unique hierarchical microstructures of the Morpho butterfly wing (MBW) exhibit angle independent blue iridescence. Biomimicking these microstructures and turning them into functional photonic crystals (PhCs) have fascinated scientists yet remain challenging. Here, a phototunable PhC is fabricated by depositing the azobenzene-containing linear liquid crystal polymer (LLCP) onto the MBW template. Thanks to the excellent mechanical properties and deformability of LLCP, the generated 3D bilayer microstructures demonstrate hierarchical deformation upon UV light irradiation, leading to a blueshift of the reflection peak (70 nm) and a remarkable change of reflectance (40%). This phototunable PhC may have potential applications in pigments, cosmetics, and sensors.
