Butterfly effects: novel functional materials inspired from the wings scales.

摘要: Through millions of years evolutionary selection, nature has created biological materials with various functional properties for survival. Many complex natural architectures, such as shells, bones, and honeycombs, have been studied imitated in the design fabrication enhanced hardness stiffness. Recently, more researchers started to research wings butterflies, mostly because their dazzling colors. It was found that most these iridescent colors are caused by periodic photonic structures on scales make up surfaces wings. These recently become a focus multidiscipline promising applications display structural colors, advanced sensors, crystals, solar cells. This paper review aims provide perspective overview inspired wing recent years.
