| 摘 要： | 黄斑大蚊的翅膀、腿表面有很好的超疏水性, 水滴在其表面的静态接触角分别为150°,155°, 滚动角接近5°, 通过扫描电子显微镜观察发现, 在黄斑大蚊的翅膀、腿表面分布有大量呈规则排列的微纳米级复合凹槽、乳突, 复合结构及其表面的低表面能物质的协同作用使其表面具有良好的超疏水性, 这一特性使黄斑大蚊能在潮湿的环境中自由生存. 本文用 Cassie 理论对这种超疏水性进行了理论分析.

| Abstract: | The Genus species mosquito exhibits perfect superhydrophobicity on the surface of its wings and legs, with contact angles of 150° and 155°, respectively. The glide angle is approximately 5°. Many regularly arranged composite grooves and mastoids were found on these surfaces through observations with a field emission scanning electron microscope. Superhydrophobicity formed because of the cooperative effects of composite structures and low surface energies. These features of superhydrophobicity enable the mosquito to live freely in a humid atmosphere; we have discussed the superhydrophobicity based on Cassie's theory. |
