In nature, many organisms can effectively fix to contact substrates and move and prey in complex living environments, such as underwater, seawater, and tidal environments, owing to special secreted chemical components and/or special micro/nanostructures on the adhesive surface of these organisms. Inspired by the adhesive performance of organisms, extensive research related to adhesive components and adhesive surfaces has been conducted recently. To better understand the underlying adhesive mechanisms and facilitate further continuous inspiration, a brief overview of recent wet/underwater adhesive materials is provided herein. First, the adhesive processes and underlying mechanisms of commonly researched organisms, such as mussels, octopuses, clingfish, and tree frogs, are discussed, and the corresponding bioinspired artificial adhesives are presented. Then, the applications of these bioinspired adhesives, such as intelligent robots (signal monitoring and sensing devices), wearable devices (including wet climbing and electronic skin), biomedicines (including wound dressings, bone adhesion, and rapid hemostasis), are presented and summarized. Finally, we offer our perspective on the future challenges and development of bioinspired artificial adhesives.

仿生水下/湿粘合剂的作用机理及应用

在自然界中，许多生物可以有效地固定接触基质，在水下、海水、潮汐环境等复杂的生活环境中移动和捕食，这是由于这些生物的粘附表面具有特殊的分泌化学成分和/或特殊的微/纳米结构。 . 受生物体粘合性能的启发，最近对粘合成分和粘合表面进行了广泛的研究。为了更好地理解潜在的粘合机制并促进进一步的持续灵感，本文提供了最近的湿/水粘合材料的简要概述。首先，讨论了贻贝、章鱼、粘鱼和树蛙等常见生物的粘附过程和潜在机制，并提出了相应的仿生人造粘合剂。然后，介绍和总结了这些仿生粘合剂的应用，如智能机器人（信号监测和传感装置）、可穿戴设备（包括湿爬和电子皮肤）、生物医学（包括伤口敷料、骨粘连和快速止血）。 . 最后，我们对仿生人工粘合剂的未来挑战和发展提出了自己的看法。
