“…[1][2][3][4][5][6][7][8][9] Synthetic polymers capable of selfreporting and self-healing mechanical damages are regarded as smart and reliable materials with potential applications in many fields, such as biomedicine, flexible electronics, and prevention of metal corrosion, among others. 3,6,[10][11][12][13][14] The materials used in aquatic and marine environments are often exposed to dark, high-pressure, and potentially dangerous underwater conditions, making mechanical damage to these materials inevitable. So far, the research on self-healing underwater materials has achieved initial results, and scientists have developed several underwater self-healing materials based on boronic-ester/boroxine bonds, [15][16][17] hydrogen bonds, 16,[18][19][20] or dipole-dipole/ion-dipole interactions.…”
