经过数十亿年的进化，生物体已经发展出具有可切换粘附力的专门生物结构，用于各种目的，包括攀爬，栖息，捕食，感知和保护。根据粘合机理，可转换粘合剂可分为四类：基于机械的粘合、液体介导的粘合、物理驱动的粘合和化学增强的粘合。模仿这些生物结构可以创造具有可切换粘附的智能材料，吸引了机器人，传感器，先进药物递送，蛋白质分离等许多工程应用。在开发具有可切换粘附的生物启发材料方面取得了进展，这些材料通过外部刺激如电信号，磁场，光，温度，pH值，本文综述了仿生设计与合成具有可切换粘附性的材料和器件的最新进展。潜在的机制，设计原则，和未来的发展方向进行了讨论的高性能智能表面与切换粘附。
Living organisms have evolved, over billions of years, to develop specialized biostructures with switchable adhesion for various purposes including climbing, perching, preying, sensing, and protecting. According to adhesion mechanisms, switchable adhesives can be divided into four categories: mechanically-based adhesion, liquid-mediated adhesion, physically-actuated adhesion and chemically-enhanced adhesion. Mimicking these biostructures could create smart materials with switchable adhesion, appealing for many engineering applications in robotics, sensors, advanced drug-delivery, protein separation, etc. Progress has been made in developing bioinspired materials with switchable adhesion modulated by external stimuli such as electrical signal, magnetic field, light, temperature, pH value, etc. This review will be focused on new advance in biomimetic design and synthesis of the materials and devices with switchable adhesion. The underlying mechanisms, design principles, and future directions are discussed for the development of high-performance smart surfaces with switchable adhesion.
