Abstract
With development of solar technology, high absorbance is no longer a hard problem in solar heat utilization. Many solar absorbing coating can easily get absorbance over 90%, but the coating materials and their manufacturing processes may harm seriously to human and environment. A typical plateau butterfly-- Lycaenidae was studied with bionic method in this work. It has considerable solar absorbing capacity for the physical microstructure in its wing scales but not chemicals. The 3D microstructure of the wing scales was measured and analyzed with SEM (Scanning Electronic Microscope) and TEM (Transition Electronic Microscope). The solar absorbing mechanism of the ridge and bottom microstructure was analyzed respectively based on geometrical optics and photon crystal theories. This study may promote solar heat utilization through a bionic structural material way.
