THERMAL OSCILLATION ARISING IN A HEAT SHOCK OF A POROUS HIERARCHY AND ITS APPLICATION

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