摘要:: 本文讲述了以裳凤蝶前翅(T_FW)和宽带凤蝶前翅(P_FW)为模板，通过化学合成方法制备了具有三维减反射准周期性微纳结构的金属(Au_T_FW、Ag_T_FW、Cu_T_FW)和碳基金属(Ag@C_T_FW)功能材料。通过XRD检测复合材料的组分和晶型；通过SEM和TEM检测了复合材料的表面形貌；通过HRTEM和SAED检测了复合材料的晶体结构。结果表明：复合材料具有优异的加强宽波段红外吸收性能。与性能优异的太阳光吸收材料BlueTec eta plus_Cu相比，300-2500nm,平均光吸收有所增强；2.5μm-15μm中红外，平均光吸收增强几十倍。此外也测试了裳凤蝶前翅和宽带凤蝶前翅的空白实验做对照，说明了性能优异的功能材料与性能优异的功能结构相结合，实现性能的提升、扩展及革新的可行性。

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.
