Dual-hard phase structures make mechanically tough and autonomous self-healable polyurethane elastomers

Flexible preparation of PA6-based thermoplastic elastomer filaments with enhanced elasticity, melt spinnability and transparency enabled by high-molecular-weight soft segments

“…13 and 14(a–d), the HS-TPAE-55 filaments exhibit a high elongation at break, which is much larger than the maximum tensile strain of garments during application and processing, and the tensile strength and elastic resilience are approximately equal to those of Spandex®. 38 These results indicate that HS-TPAE-55 filaments can be used as elastic filaments to manufacture fabrics.…”

High Toughness, Multi-dynamic Self-Healing Polyurethane for Outstanding Energy Harvesting and Sensing

“…The introduction of metal coordination bonds serves to enhance the mechanical properties of the material and is expected to improve its elasticity. 43 During loading, hydrogen bonds and metal coordination bonds function as sacrificial bonds to dissipate energy and recombine after unloading to restore the mechanical properties of the material. 44 Cyclic tensile tests with progressively increasing strain were performed without any dwell time between loadings (Figure 2c−e).…”

Stretchable and self-healing electronic skin based on a piezoelectric/triboelectric polyester elastomer for deep and superficial sensation

“…[32][33][34] Thus, the comprehensive and precise sensing of supercial sensations such as touch and stretch, as well as deep sensations such as position and state, can be achieved simultaneously. 35 Furthermore, the exible backbone and restricted crystallinity make PBES exhibit similar characteristics to human skin, 36,37 including stretchability with elastic elongation as high as 300%, self-healing ability with a recovered electric performance of 90% in 10 minutes, and biocompatibility with a cell relative growth rate higher than 80%. The synchronous realization of deep and supercial sensation and restoration of properties of human skin indicate that PBES holds immense promise for multi-functional and comprehensive human bionics, making it highly suitable for applications in the elds of bionics and articial intelligence.…”
