摘要:

本文講述了以裳鳳蝶前翅(T_FW)和寬帶鳳蝶前翅(P_FW)為模板，通過化學合成方法制備了具有三維減反射準周期性微納結構的金屬(Au_T_FW、Ag_T_FW、Cu_T_FW)和碳基金屬(Ag@C_T_FW)功能材料。通過XRD檢測復合材料的組分和晶型；通過SEM和TEM檢測了復合材料的表面形貌；通過HRTEM和SAED檢測了復合材料的晶體結構。結果表明：復合材料具有優異的加強寬波段紅外吸收性能。與性能優異的太陽光吸收材料BlueTec eta plus_Cu相比，300-2500nm,平均光吸收有所增強；2.5μm-15μm中紅外，平均光吸收增強幾十倍。此外也測試了裳鳳蝶前翅和寬帶鳳蝶前翅的空白實驗做對照，說明了性能優異的功能材料與性能優異的功能結構相結合，實現性能的提升、擴展及革新的可行性。

Abstract:

the study shows that in the chemical synthesis method, set butterfly-wings as template to fabricate the composite functional materials, possessed metal and carbon base metal respectively, in 3-D antireflection quasi-periodicity micro structure. To investigate the constituent of functional materials, XRD is used. And we investigate the feature of it by SEM and TEM. Besides, we observes the crystal structure by HRTEM and SAED. The result exhibits: the functional material possessed excellent property in enhancing absorption of wide-band infrared. Compare with excellent absorption material named BlueTec eta plus_Cu, the functional material has some enhancement from 300 to 2500 nm wavelength and has huge enhancement from 2.5 to 15 μm wavelength. What’s more, this study also observes the absorption of butterfly-wings only. All this result shows that it is feasible to combine excellent functional material with excellent functional structure to achieve the huge enhancement of property.
