在这项工作中，我们报告了一种简单的方法来制造智能聚合物，该聚合物采用 Morpho 蝴蝶翅膀的分层光子结构设计，以呈现能够随温度调节颜色的高性能。该材料通过将功能性温度响应性聚(N-异丙基丙烯酰胺)-共聚丙烯酸(PNIPAm-co-AAc)与Morpho蝴蝶翅膀的生物光子晶体(PC)结构相结合来组装，从而产生功能性聚合物与天然PC结构之间的协同效应。它们的协同作用体现在 PNIPAm-co-AAc 的相变（随温度变化而变化）中，可以改变 PC 的纳米结构，从而进一步导致改性分级光子结构的可逆光谱响应特性。这里提出的具有成本效益的仿生技术凸显了通过共组装智能聚合物和生物层次结构来制造更具刺激响应性的功能材料的光明前景，它将成为纳米智能生物材料发展的重要平台。
In this work, we report a simple method to fabricate smart polymers engineered with hierarchical photonic structures of Morpho butterfly wing to present high performance that are capable of color tunability over temperature. The materials were assembled by combining functional temperature responsivity of poly(N-isopropylacrylamide)-co-acrylic acid (PNIPAm-co-AAc) with the biological photonic crystal (PC) structure of Morpho butterfly wing, and then the synergistic effect between the functional polymer and the natural PC structure was created. Their cooperativity is instantiated in the phase transition of PNIPAm-co-AAc (varying with the change of temperature) that can alter the nanostructure of PCs, which further leads to the reversible spectrum response property of the modified hierarchical photonic structures. The cost-effective biomimetic technique presented here highlights the bright prospect of fabrication of more stimuli-responsive functional materials via coassembling smart polymers and biohierarchical structures, and it will be an important platform for the development of nanosmart biomaterials.
