Abstract
Scanning electron microscope and optical contact angle measuring instruments were used to investigate the microstructure and wettability of geometric non-smooth structure of dragonfly wing surface. Results show that the geometric non-smooth structure of dragonfly wing surface is one part of epicuticle, some organic solvents can effectively dissolve the main ingredient of non-smooth structure. The hydrophobicity of dragonfly wing surface is induced by the co-coupling of the non-smooth structure and the waxy layer covering.
