Abstract
Wearable and flexible optoelectronic devices are rapidly advancing toward human‐interactive applications. However, their operational lifespan is often limited by mechanical damage, interface delamination, and environmental influences. Existing encapsulation methods provide only partial protection and lack autonomous repair capabilities under real‐world conditions. In this study, we present a bioinspired self‐healing polymer (SHP) composite modeled after butterfly wings. This material features a cooperative network of hydrogen bonds, disulfide exchange, and π–π interactions, enabling rapid self‐healing at room temperature without external stimuli. The SHP demonstrates outstanding stretchability (4950%), high toughness (30.47 MJ m−3), and environmental resilience, with healing efficiencies of 98% in water, 89% in phosphate buffer saline, and 84% at −5°C. When integrated into emissive layers, SHP‐based light emitting diodes (LEDs) achieve high luminance (9598 cd m− 2) and an external quantum efficiency (EQE) of 10.52%. Additionally, SHP‐encapsulated perovskite‐based integrated SHP LEDs reach a peak EQE of 8.43% and current efficiency of 20.67 cd A−1. The flexible, crack‐resistant encapsulation effectively prevents moisture ingress and mechanical failure, maintaining 96% luminance after 400 bending cycles. This self‐sustained ISHP‐based strategy enhances device durability, reduces electronic waste, and supports the development of autonomous, repairable optoelectronic systems for wearable displays, smart textiles, and soft robotics.
