The field of adhesion has revealed a significant impact on numerous applications such as wound healing, drug delivery, electrically conductive adhesive, dental adhesive, and wood industry. Nanotechnology has continued to be the primary means to achieve adhesion. Among them, biological systems based on the unique structure of the nano-levels have developed excellent adhesion capabilities after billions of years of evolution and natural selection. Therefore, the research on bionic adhesion inspired by biological systems has gradually emerged. This review firstly focuses on the mechanism of adhesion, and secondly reports the effects of different nanomaterials on adhesion properties. Then based on the structure of mussels, geckos, tree frogs, octopuses, and other organisms, the research progress of biomimetic nanotechnology to achieve adhesion is summarized. Finally, the applications, challenges, and future directions of nanotechnology in new adhesive materials are provided.
黏附领域揭示了其对众多应用的重大影响，例如伤口愈合、药物输送、导电胶、牙科用胶和木材工业。纳米技术一直是实现黏附的主要手段。其中，基于纳米级独特结构的生物系统经过数十亿年的进化和自然选择，发展出了出色的黏附能力。因此，受生物系统启发的仿生黏附研究逐渐兴起。本文首先聚焦黏附的机理，其次报告了不同纳米材料对黏附性能的影响。然后，基于贻贝、壁虎、树蛙、章鱼等生物体的结构，总结了仿生纳米技术在实现黏附方面的研究进展。最后，提供了纳米技术在新型黏附材料中的应用、挑战和未来方向。
