Supertough spontaneously self-healing polymer based on septuple dynamic bonds integrated in one chemical group
文献摘要：
The development of spontaneously self-healing materials with excellent mechanical properties remains a formidable challenge despite the extensive interest in such materials.This is because the self-healing and mechanical properties of a material are usually optimized via contradictory routes.The present study demonstrated a supertough spontaneously self-healing polymer,Fe-(2,6-diacetylpyridine dioxime)-urethane-based polyurethane(Fe-PPOU)based on septuple dynamic bonds integrated in one chemical group.A synergistic effect was induced by the presence of multiple dynamic crosslinking points,which comprised the integrated dynamic interactions,and the hidden lengths of the folded polymeric chains in Fe-PPOU.Thus,the mechanical and self-healing properties of the polymer were simultaneously optimized.Fe-PPOU demonstrated the highest reported toughness(139.8 MJ m-3)among all the room-temperature spontaneously self-healing polymers with a nearly 100％healing rate.Fe-PPOU exhibited instant(30 s)self-healing to reach a strength of 1.6 MPa that was higher than the original strength of numerous recently reported self-healing polymers.
