The development of underwater remote stimulus-responsive self-healing polymer materials for applications in inaccessible and urgent situations is very challenging because water can readily disturb traditional noncovalent bonds absorb heat, UV light, IR electromagnetic wave energy at the band micrometers millimeters. Herein, visible-light-responsive diselenide are employed as healing moieties to produce a water-enhanced elastomer triggered by blue laser, which possesses excellent transmission capability. During healing, strain break reaches ∼200% 5 min its toughness almost fully recovers within 1 h, estimated be fastest reported date silicone elastomers with efficiency above 90%. pipeline sealing instantly accomplished diselenide-containing laser 3 m away, thereby providing direction future emergent applications.
