Abstract

The Guizhou Gastromyzontidae showed extraordinary normal adhesion and anisotropic friction on wet and slippery surfaces in the torrential stream. In this study, the surface microstructures of adhesive disc of the Guizhou Gastromyzontidae were characterized firstly by using the Scanning Electron Microscopy (SEM). It had been found that the fin rays of the fish were composed of the hexagonal pad-like unculi, setae arrays and micro-pores. Then, inspired by the surface structures of the adhesive disc of Guizhou Gastromyzontidae, the artificial adhesive discs with surface microstructures were designed and fabricated by using the 3D printing and molding technology. The regular disc with no surface microstructures was also fabricated for comparison study. The adhesion properties of two different disc samples were investigated in water condition on substrates with various roughnesses. The results show that the bionic adhesive discs with composite microstructures have good adhesion properties in water condition. The proposed adhesive disc could have potential applications for underwater robotics.

一种受贵州腹足虫科启发的用于激流免疫运动的仿生粘接圆盘

贵州麻蝇科在水流湿滑表面表现出异常正常的粘附和各向异性摩擦。本研究首次利用扫描电子显微镜(SEM)对贵州麻蝇科粘盘的表面微观结构进行了表征。研究发现，该鱼的鳍鳍是由六角形的垫状鳍片、刚毛排列和微孔组成的。然后，以贵州麻蝇科粘接盘的表面结构为灵感，采用3D打印成型技术设计制作了具有表面微结构的人工粘接盘。并制作了无表面微结构的规则圆盘进行对比研究。研究了两种不同的圆盘样品在不同粗糙度的基体上在水中的粘附性能。结果表明，复合微结构仿生粘接片在水中具有良好的粘接性能。所提出的粘接圆盘可能在水下机器人中有潜在的应用。
