摘要：

        Self-healing soft electronic material composition is crucial to sustain the device long term durability. The fabrication of self-healing soft electronics exposed to high moisture environment is a significant challenge that have yet to be fully achieved. The supramolecular water-assisted self-healing polymer (WASHP) films possessed rapid self-healing kinetic behavior and high stretchability due to a reversible dissociation–association process. In comparison with the pristine room-temperature self-healing polymer, our WASHP demonstrated favorable mechanical performance at room temperature and a short self-healing time of 1 h; furthermore, it achieves a tensile strain of 9050%, self-healing efficiency of 95%, and toughness of 144.2 MJ/m³. As a proof of concept, a versatile WASHP-based light-emitting touch-responsive device (WASHP-LETD) and perovskite quantum dot (PeQD)-based white LED backlight were designed. The WASHP-LETD had favorable mechanical deformation performance under pressure, bending, and strain, whereas the WASHP-PeQDs exhibited outstanding long-term stability even over a period exceeding 1 year in a boiling water environment. This research provides a mechanically robust approach for producing eco-friendly, economical, and waterproof e-skin device components. Second, the perovskite and SHP-induced shattered–repaired perovskite glass substrate show the lowest lasing threshold values of 1.24 and 8.58 µJ cm⁻², respectively. This work provides an integrative and in-depth approach to exploiting SHP with intrinsic and entropic self-healing capabilities combined with HPNCs to develop robust and reliable soft-electronic backlight and laser applications.
