Abstract

A building or a bridge might collapse after a heat shock. This paper shows that a porous hierarchy of a coating can effectively prevent a building or a bridge from such damage. A cocoon’s geometrical structure is studied and its resistance to the heat shock is revealed by a thermal oscillator. The theoretical model reveals an extremely low frequency of the thermal oscillator, which is very important for cocoons’ biomechanism, especially in the heat insulation function. At the same time, it shows that the cocoons have the best thickness to protect the pupa from the environment. In addition, surface temperature measurement of hierarchical mulberry leaves is performed. This work provides new insights into biomimetic design of the protective building and coatings.

多孔结构热冲击引起的热振荡及其应用

建筑物或桥梁可能在热休克后倒塌。本文表明，多孔分层涂层可以有效地防止建筑物或桥梁遭受这种破坏。研究了蚕茧的几何结构，并用热振仪揭示了蚕茧对热冲击的抵抗能力。理论模型揭示了热振子的极低频率，这对茧的生物机理，特别是隔热功能非常重要。同时也说明茧的厚度对于保护蛹不受环境影响是最好的。此外，还对分层桑叶进行了表面温度测量。这项工作为防护建筑和涂料的仿生设计提供了新的见解。
