蝶翼表面结构对辐射制冷性能的影响
Effects of Butterfly Wing Surface Structures on Radiative Cooling Performance
摘要
Abstract
Scanning electron microscopy is used to characterize the micro morphology of different color areas on the surface of the Polyura eudamippus,Parantica aglea and Papilio xuthus.The reflectivity and transmissivity of different color regions on the wing surfaces of different butterflies were measured by ultraviolet spectrometer.The experimental results show that the surface microstructure of the wing has a great influence on the reflectivity,the transmissivity,the absorptivity,and the extinction coefficient.The maximum reflectivity of the silver and white regions of the wing of Polyura eudamippus is more than 50%at low wavelengths.The transmissivity of the Polyura eudamippus black region,the Parantica aglea silver region and the Papilio xuthus white region are less than 20%in the high wavelengths.The absorptivity of the Polyura eudamippus black region and the Papilio xuthus blue region are more than 90%.The extinction coefficients the black region of the Polyura eudamippus and the blue area of the Papilio Xuthus are higher atin the low wavelengths.In a word,the surface structure of the black region of the Polyura eudamippus and the blue region of the Papilio xuthus has good light radiative cooling performance.关键词
