A highly stretchable, fast self-healing elastomer with fast, tough, repeatable adhesion

Integration of high toughness, fracture resistance, and fast self-healing, as well as robust adhesion is critically required for flexible electronics, healthcare monitoring, and electronic skins. However, it still remains a critical challenge to combine these significant functions into one material. Here, we synthesize an elastomer by copolymerizing two acrylate monomers containing functional groups and established hierarchical dipolar in-teractions and hydrogen bonds between C-F, C=O, -O-CH3, and C-H groups with different bonding strengths, which successfully not only combines with high toughness (31.41 +/- 1.12 MJ m(3)), outstanding crack resistance (fracture energy: 10252 +/- 208 J m(2)), fast self-healing (completely restore within 30 min at room temperature), but also with fast, repeatable, and toughness adhesion to different substrates, e.g. PMMA, Aluminum, glass, steel, and PTFE. The PF4M6 demonstrates great sensing performance in detecting human motion. Overall, this work provides some insights for preparing high-performance, healing, and adhesive elastomer materials applied in electronics, adhesives, and interface materials.
