摘要/Abstract

摘要： 针对一次性蜡模或光刻工艺制备方向性黏附阵列效率低且工艺复杂的问题，提出了基于微纳3D打印技术的楔形微结构阵列高效制备工艺，制备的仿生楔形阵列材料具有良好的黏附性能和方向性黏附特性。首先，仿生设计了具有方向性特性的楔形阵列黏附结构。然后，利用微纳3D打印技术加工了相应的微结构阵列模具，发展了仿生黏附材料制备工艺，分析了楔形结构的轮廓精度。最后，搭建了实验测试平台，研究了剪切方向、剪切距离、预压力、脱附速度等因素对黏附性能的影响规律。结果表明，仿生楔形阵列黏附材料具有显著的方向性黏附特性，验证了微纳3D技术用于制备仿生方向性干黏附材料的可行性。

Abstract: In order to solve the problems of low efficiency and complex processes of preparing directional adhesive arrays using disposable wax mold or photolithography, an efficient preparation process of wedge-shaped micro structure arrays was proposed based on micro-nano 3D printing technology, and the prepared wedge-shaped array material possessed good adhesion properties and directional adhesion properties. First, the bio-inspired wedge array adhesion structure with directional characteristics was designed. Then, the corresponding micro-structure array mold was fabricated by micro-nano 3D printing technology, the preparation processes of the bio-inspired adhesive material were developed, and the contour accuracy of the wedge-shaped structure was analyzed. Finally, an experimental test platform was constructed to study the influences of shear direction, shear distance, preload, desorption speed and other factors on the adhesion performance. The results demonstrate that the bio-inspired wedge-shaped array adhesive materials have significant directional adhesion properties, which verify the feasibility of the micro-nano 3D printing technology in preparing bio-inspired directional dry adhesive materials.

Key words: bio-inspired dry adhesive, directional adhesion, wedge array, micro-nano 3D printing
