【摘要】：阐述了以裳凤蝶前翅(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和碳基金属功能材料。通过XRD检测复合材料的组分和晶型;通过SEM和TEM观察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Blue Tec eta plus_Cu相比,对300~2500 nm波长光,平均光吸收有所增强;对2.5~15μm中红外光,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]:Metal and carbon-based metal functional materials with three dimensional antireflection quasi periodic microstructures were prepared by chemical synthesis using T _ p _ FW) and P _ S _ F _ W) as templates. The composition and crystal form of the composites were detected by XRD. The surface morphology of the composites was observed by SEM and TEM. The crystal structure of the composite was tested by HRTEM and SAED. The results show that the composite has excellent infrared absorption performance in the wide band. Compared with the Blue Tec eta plus_Cu, the wavelength of 300nm and 2500nm is better than that of the Blue Tec eta plus_Cu. The average light absorption was increased, and the average light absorption was increased by tens of times in the medium infrared light of 2.5 渭 m. In addition, the blank experiments of the front wing and the broad-band front wing of Pteris mongolicum were also tested and compared. The feasibility of improving, expanding and innovating the performance of functional materials with excellent functional structure is explained.
