摘要:

 傳統設計與制備技術手段往往難以實現預期精細結構與功能構筑，從而限制了材料結構-性能之間新現象的發現與新機理的建立。借用經億萬年自然優化的生物自身多層次、多維和多尺度的本征結構為模板，通過物理和化學手段，在保留生物精細分級結構的同時，置換生物模板的化學組分為所需功能組分，利用生物精細結構與人工組分之間的耦合關系，可制備既遺傳自然生物精細形態，又有人為賦予特性的新材料——遺態材料。圍繞具有蝶翅精細結構的遺態光功能材料，分別以金屬-半導體功能蝶翅的紅外吸收增強及光熱轉換、金屬功能蝶翅的表面等離子體拉曼增強為例，介紹了遺態材料的設計思路、制備方法、性能表征及相關機理探索過程。相關思路與方法為解決分級精細結構難以制備的難題提供了新途徑，并為新材料構型設計提供了前瞻性思路和原理驗證。

Abstract:

Traditional design and manufacture method is less likely to duplicate the expected elaborate structures and functions, which seriously hinders the discovery of new phenomenon and the establishment of new mechanism between structures and functions. The chemical constituents within the organism can be replaced with the desired functional constituents by using the multi-level, multi-dimensional and multi-scale intrinsic bio-structure as template, through physical and chemical process. This innovative material, which endows the desired function while maintains the original bio-structure at the same time, is named morpho-genetic material. This manuscript presents the design, manufacture, characterization and mechanism of optical function morpho-genetic material, illustrates by two typical examples：metal-semiconductor functional wings enhanced infrared absorption and photothermal conversion, metal wing surface enhanced Raman scattering. The research thought and synthesis method mentioned here offer a new solution for the synthesis of multi-level fine structure. Furthermore, it provides a foresight and theoretical support for proposal of the novel material.
