Reversible adhesion is the key functionality to grip, place, and release objects nondestructively. Inspired by nature, micropatterned dry adhesives are promising candidates for this purpose and have attracted the attention of research groups worldwide. Their enhanced adhesion compared to nonpatterned surfaces is frequently demonstrated. An important conclusion is that the contact mechanics involved is at least as important as the surface energy and chemistry. In this paper, the roles of the contact geometry and mechanical properties are reviewed. With a focus on applications, the effects of substrate roughness and of temperature variations, and the long‐term performance of micropatterned adhesives are discussed. The paper provides a link between the current, detailed understanding of micropatterned adhesives and emerging applications.

工程微图案干胶：从接触理论到处理应用

可逆的附着力是无损抓取，放置和释放物体的关键功能。受自然界的启发，微图案干胶是用于此目的的有前途的候选材料，并已引起全球研究小组的关注。与无图案的表面相比，它们的附着力得到了提高。一个重要的结论是，所涉及的接触力学至少与表面能和化学同等重要。在本文中，对接触几何形状和机械性能的作用进行了综述。着重于应用，讨论了基材粗糙度和温度变化的影响，以及微图案胶粘剂的长期性能。本文提供了当前对微图案胶粘剂的详细了解与新兴应用之间的链接。
