Mussels attach to solid surfaces in the sea. Their adhesion must be rapid, strong, and tough, or else they will be dislodged and dashed to pieces by the next incoming wave. Given the dearth of synthetic adhesives for wet polar surfaces, much effort has been directed to characterizing and mimicking essential features of the adhesive chemistry practiced by mussels. Studies of these organisms have uncovered important adaptive strategies that help to circumvent the high dielectric and solvation properties of water that typically frustrate adhesion. In a chemical vein, the adhesive proteins of mussels are heavily decorated with Dopa, a catecholic functionality. Various synthetic polymers have been functionalized with catechols to provide diverse adhesive, sealant, coating, and anchoring properties, particularly for critical biomedical applications.

受贻贝启发的粘合剂和涂料


贻贝附着在海中的固体表面上。它们的附着力必须快速、牢固且坚韧，否则它们将被下一个来袭的波浪移动并粉碎成碎片。鉴于缺乏用于湿极性表面的合成粘合剂，人们付出了很多努力来表征和模仿贻贝所使用的粘合剂化学的基本特征。对这些生物体的研究发现了重要的适应性策略，有助于规避水的高介电和溶剂化特性，这些特性通常会阻碍粘附。从化学角度来看，贻贝的粘附蛋白大量装饰有多巴（一种儿茶素功能）。各种合成聚合物已用儿茶酚进行功能化，以提供不同的粘合剂、密封剂、涂层和锚定性能，特别是对于关键的生物医学应用。
