Polymer materials that are able to self‐heal in humid conditions or even in water are highly desirable for their industrial applications. However, the development of underwater self‐healing polymer materials is very challenging since water molecules can readily disturb traditional noncovalent bonds, such as saturate the hydrogen bonds, coordinate with the metal cation, as well as solvate the ions. Here, a new type of dipole–dipole interactions is employed as the driving force, combining with highly polar and hydrophobic fluorinated polymers, to successfully demonstrate an underwater self‐healing elastomer. The polymer materials are transparent and stretchable. They can remain stable underwater for months without significant decay of mechanical properties. Upon mechanical damage, the material is able to self‐heal automatically in air, underwater, and under very harsh aqueous conditions (including seawater, highly acidic media, and highly basic media, etc.).

具有高弹性的透明弹性体，能够在水下自动自我修复

能够在潮湿条件下甚至在水中自愈的聚合物材料对于其工业应用是非常理想的。但是，水下自愈聚合物材料的开发非常具有挑战性，因为水分子很容易干扰传统的非共价键，例如使氢键饱和，与金属阳离子配合以及使离子溶剂化。在这里，一种新型的偶极-偶极相互作用被用作驱动力，并结合了高极性和疏水性氟化聚合物，成功地展示了一种水下自修复弹性体。聚合物材料是透明的和可拉伸的。它们可以在水下保持稳定数月，而不会显着降低机械性能。受到机械损坏时，该材料能够在空气，水下，
