The heat transfer properties of a material strongly rely on its surface structure. The wings of the Morpho butterfly have a unique surface structure with features of order and disorder. In this work, the surface temperature and radiative heat flux of Morpho butterfly wings with structural colour when a ceramic heater attached to the opposite surface of the wings was heated to 250 °C were evaluated in terms of their heat transfer properties. Morpho menelaus butterfly (MM) wings and Cithaerias (CE) wings with no periodic structure on their surface, were used as samples. The MM wings had higher surface temperature and radiative heat flux than the CE wings, which is the first report of heat transfer properties of the wings. The surface structure of the MM wings was changed by heat treatment in order to investigate the effect of the surface structural change on their heat transfer properties. The treatment changed the colour of the wings to red and brown, distorting the periodic structure. The radiative heat flux increased due to the change in the structure on their surface. XPS spectra revealed that the treatment leads to a slight change in the chemical structure of the wings. The spectral analyses results showed there was no obvious change in the mid-infrared absorbance. The heat radiative properties of the MM wings were strongly influenced by the surface structural changes due to the heat treatment.

Morpho蝴蝶翅膀的传热特性以及这些特性对机翼表面结构的依赖性

材料的传热性能强烈依赖于其表面结构。大闪蝶的翅膀具有独特的表面结构，具有有序和无序的特征。在这项工作中，当安装在翅膀相对表面的陶瓷加热器加热到 250 °C 时，具有结构颜色的Morpho蝴蝶翅膀的表面温度和辐射热通量就其传热性能进行了评估。Morpho menelaus蝴蝶 (MM) 翅膀和Cithaerias(CE) 在其表面上没有周期性结构的机翼被用作样品。MM机翼比CE机翼具有更高的表面温度和辐射热通量，这是机翼传热特性的首次报道。通过热处理改变了MM机翼的表面结构，以研究表面结构变化对其传热性能的影响。处理将翅膀的颜色变为红色和棕色，扭曲了周期性结构。由于其表面结构的变化，辐射热通量增加。XPS 光谱显示，处理导致机翼化学结构发生轻微变化。光谱分析结果表明中红外吸光度没有明显变化。
