題目:Super Tough and Spontaneous Water-Assisted Autonomous Self-Healing Polymer for Underwater Wearable Perovskite Based-Electronics
高堅韌之水輔助自癒合高分子材料及其應用於可穿戴之鈣鈦礦光電元件

內容摘要:
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.
