Self-healing soft electronic material composition is crucial to sustain the device long-term durability. The fabrication of self-healing electronics exposed high moisture environment a significant challenge that has yet be fully achieved. This paper presents novel concept water-assisted room-temperature autonomous mechanism based on synergistically dynamic covalent Schiff-based imine bonds with hydrogen bonds. supramolecular polymer (WASHP) films possess rapid kinetic behavior and stretchability due reversible dissociation-association process. In comparison pristine polymer, WASHP demonstrates favorable mechanical performance at room temperature short time 1 h; furthermore, it achieves tensile strain 9050%, efficiency 95%, toughness 144.2 MJ m-3 . As proof concept, versatile WASHP-based light-emitting touch-responsive (WASHP-LETD) perovskite quantum dot (PeQD)-based white LED backlight are designed. WASHP-LETD deformation under pressure, bending, strain, whereas WASHP-PeQDs exhibit outstanding stability even over period exceeding one year in boiling water environment. provides mechanically robust approach for producing eco-friendly, economical, waterproof e-skin components.
