通过体视显微镜、扫描电子显微镜、傅里叶变换红外光谱对水黾腿表面的形态、结构和成分进行了定性定量研究,采用视频光学接触角测量仪以及Cassie模型对水黾多腿并排的表面润湿性能进行了测量与分析.结果表明,水黾腿表面均匀分布有刚毛,刚毛表面有螺旋状沟壑；水黾多腿并排后的表面接触角达(152.9±1.0)o,表明该表面具有超疏水性；Cassie模型计算结果表明,水黾多腿并排后的超疏水性是其腿部表面有机物质和表面微观结构耦合作用的结果,并排测量方式对其影响较小.

Stereoscopic microscope, scanning electron microscope(SEM), Fourier transform infrared spec-troscopy( FTIR) and optical contact angle measuring instrument were adopted to study the morphology, struc-ture and composition of water strider's legs. Optical contact angle measuring instrument and Cassie model were used to study and analyze the wetting properties of side-by-side water strider's leg surface. The results show that the leg is covered with large numbers of tiny chitinous setae and the surfaces of the setae are marked with helical grooves. The contact angle is (152. 9±1. 0)o. It indicates that side-by-side legs own the superhy-drophobicity, and the Cassie model results indicate that the superhydrophobicity of side-by-side water strider's leg is induced by the multivariate coupling of organic matter, microstructure, and has no relationship with the arrangement of legs.
