中文摘要 開發具有超拉伸性、堅固性和快速自癒等特殊屬性的高性能軟電子裝置具有重要意義。 然而，在能量產生器具有卓越自我修復能力的同時實現極高的拉伸性仍然是一項艱鉅的挑戰。 旨在增強拉伸性和自修復性的流行策略主要集中在聚合物主鏈工程。 為了應對這項挑戰，我們將氟基有機小分子 (3N5F) 引入聚合物基質中，在聚合物鏈上形成 π-πF 堆積和氟氫鍵。 滑動交聯劑（3N5F分子）和聚合物鏈之間形成的弱相互作用使材料具有超拉伸性（超過20,000％應變而不破裂）和快速自修復能力（僅在1小時內恢復100％的機械性質）。 為了追求超拉伸、自修復和導電複合材料，我們採用液態金屬或碳黑 (CB) 作為可拉伸導體的導電填料。 這些導體用於運動和位置感測以及能量收集摩擦奈米發電機。 這些產品表現出一致的性能，為檢測人體運動的下一代自供電電子產品領域取得了重大進展。
英文摘要 The development of highly capable soft electronic devices with exceptional attributes, including ultra-stretchability, robustness, and swift self-healing, is of great significance. However, achieving extreme stretchability at the same time as superior self-healing of energy generators remains a formidable challenge. Prevailing strategies aimed at enhancing stretchability and self-healing have predominantly focused on polymer backbone engineering. To address this challenge, we introduced fluoro-based organic small molecules (3N5F) into the polymer matrix, creating π-πF stacking and fluorine–hydrogen bonds with the polymer chains. The weak interactions formed between the sliding crosslinkers (3N5F molecules) and the polymer chains result in materials with ultra-stretchability (surpassing 20,000% strain without rupture) and rapid self-healing ability (recovering 100% of the mechanical properties within only 1 h). In the pursuit of an ultra-stretchable, self-healing, and conductive composite, we employed liquid metal or carbon black (CB) as conducting fillers for stretchable conductors. These conductors are utilized for motion and position sensing as well as for energy-harvesting triboelectric nanogenerators (TENGs). These show consistent performance, signifying a substantial advancement in the realm of next-generation self-powered electronics designed for the detection of human movement.
