Study on Micro and Nano Structure and Superhydrophobicity for Several Typical Planing Animals Legs

Article Preview

Abstract:

this paper studied superhydrophobic of water strider, water flies, water mosquitoes and water spiders legs, their contact angle were measured by the contact angle measuring instrumen, which were 161.5°,158.4°, 155.3° and 159.6° respectively, they are all superhydrophobic. Microstructure of water strider, water flies, water mosquitoe and water spiders leg was observed through scanning electron microscopy, It found that 4 typical planing animals leg are composite structure of micron scale and nanoscale, although their forms is different, they have reached the super-hydrophobic effect.
