| 中文摘要: |
| 粘合剂在潮湿环境中的局限性大大限制了它们在许多领域的广泛应用，因此，开发具备水下粘附性能的新型材料已成为研究的重点。在这方面，大自然常常为科学家提供灵感。例如，生活在海水和潮汐环境中的贻贝、沙堡蠕虫和藤壶等生物，它们依靠分泌特殊的粘附蛋白，在水下实现稳定粘附。贻贝通过足丝分泌贻贝足蛋白，将自己牢固地附着在岩石上；沙堡蠕虫通过分泌水泥蛋白，将沙砾粘附在一起，形成坚固的保护壳；藤壶则分泌水泥蛋白将基质壳牢牢固定在各种有机或无机的表面上。本文将详细总结这三种海洋生物的粘附蛋白组成、粘附过程及粘附机制，并介绍相关仿生水下粘合剂的研究进展。通过借鉴这些生物的自然粘附策略，科学家们正在探索和开发具备优异湿态粘附性能的新型粘合材料，这些材料有望在医学、海洋修复、建筑等领域获得更广泛的应用。 |

| The limitations of adhesives in humid environments greatly restrict their widespread application in many fields. Therefore, the development of novel materials with underwater adhesion capabilities has become a key research focus. In this regard, nature often serves as a source of inspiration for scientists. For example, marine organisms such as mussels, sandcastle worms, and barnacles, which inhabit seawater and tidal environments, achieve stable underwater adhesion by secreting specialized adhesive proteins. Mussels secrete mussel foot proteins through byssal threads, allowing them to firmly adhere to rocks. Sandcastle worms secrete cement proteins to bind sand grains together, forming a sturdy protective shell. Barnacles secrete cement proteins to securely attach their base shells to various organic or inorganic surfaces. This article will provide a detailed summary of the adhesive protein composition, adhesion process, and adhesion mechanisms of these three marine organisms, as well as introduce the research progress of related biomimetic underwater adhesives. By drawing inspiration from the natural adhesion strategies of these organisms, scientists are exploring and developing novel adhesive materials with excellent wet adhesion properties, which are expected to find broader applications in fields such as medicine, marine repair, and construction. |
