Wearable displays that can be applied to smart clothing systems are attracting attention as a core technology in terms of the communication between machines and humans. However, currently available displays still lack durability under random deformations of clothes. Here, we report a self-healable organic light-emitting devices (OLEDs) for smart clothing system, which can recover from the various physical deformations of clothing. The reduced luminance of damaged OLEDs can be recovered again, and the structure variation caused by repetitive motions of the OLEDs can be restored to the original shape. In addition, the operating voltage of the self-healable OLEDs is 2.9 V, which is the lowest among those reported for light-emitting devices with self-healing materials. The electroluminescence intensity at 514 nm of a damaged OLEDs is only about 14.2% of its initial value due to the formations of leakage currents around internal and external cracks. However, the electroluminescence intensity at 514 nm of a damaged device recovers to 95.3% of its initial value due to the self-healing property of the polyvinyl alcohol:Agar nanocomposite and the shape-memory property of the cross-linked polyurethane. Furthermore, we demonstrate that our newly developed self-healable OLEDs represents a new core technology for future smart clothing systems because it can self-recover from damage.

可应用于智能服装系统的可穿戴显示器作为机器与人之间通信的核心技术而备受关注。然而，目前可用的显示器在衣服随机变形下仍然缺乏耐用性。在这里，我们报告了一种用于智能服装系统的自修复有机发光器件 (OLED)，它可以从服装的各种物理变形中恢复。受损OLED的亮度降低可以再次恢复，由OLED重复运动引起的结构变化可以恢复到原来的形状。此外，自修复 OLED 的工作电压为 2.9 V，在报道的具有自修复材料的发光器件中最低。受损 OLED 在 514 nm 处的电致发光强度仅为 14 左右。由于在内部和外部裂缝周围形成漏电流，其初始值的 2%。然而，由于聚乙烯醇：琼脂纳米复合材料的自愈特性和交联聚氨酯的形状记忆特性，受损器件在 514 nm 处的电致发光强度恢复到其初始值的 95.3%。此外，我们证明了我们新开发的自修复 OLED 代表了未来智能服装系统的一项新核心技术，因为它可以从损坏中自我恢复。琼脂纳米复合材料和交联聚氨酯的形状记忆性能。此外，我们证明了我们新开发的自修复 OLED 代表了未来智能服装系统的一项新核心技术，因为它可以从损坏中自我恢复。琼脂纳米复合材料和交联聚氨酯的形状记忆性能。此外，我们证明了我们新开发的自修复 OLED 代表了未来智能服装系统的一项新核心技术，因为它可以从损坏中自我恢复。
