摘要：
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. © 2023 China Mechanical Engineering Magazine Office.
