Abstract
- • Slipping semi-crystalline hydrogen bonding arrays strategy was firstly proposed. • Ultrastretchability and outstanding toughness were achieved simultaneously. • Excellent sensitivity was achieved by compensating electronic networks. Self-healing and human-friendly electronics, with plenty of dynamic structural motifs, are desired to be ultrastretchable, highly sensitive, self-powered and responsive with external stimulus as the medium of artificial intelligence. Herein, meticulously engineered dynamic structural motifs, slipping semi-crystalline dynamic hydrogen bonding arrays (SSHAs) were firstly proposed and utilized to achieve ultrastretchable (2880 %), tough (115.7 MJ∙m−3) elastomers (PAT) with excellent actuation performance (actuation strain ≈ 37 %) and human-friendly healing temperature. For the multifunctionality, the elaborate assembly of SSHAs was also adopted to obtain three-dimensional (3D) physical networks (PAT-M) by integrating with Ti 3 C 2 T x and silver nanowire. As expected, high sensitivity (gauge factor, GF ≈ 60.6) and ultrahigh energy harvesting property (2.6 W∙m−2) were simultaneously achieved attributing to the 3D physical networks. This study not only provides a brand-new and promising strategy to develop human-friendly self-healing elastomers, but also promotes the advances of multifunctional electronics.
