| Abstract | Intelligent polymers with tough networks are of considerable significance for the development of highly proficient polymer science and technology. In this work, polymeric elastomers with integrated stretchable and self-healable characteristics were designed by cross-linking hyperbranched polymers with flexible segments. The hyperbranched polymer with multiple terminal groups provided various cross-linking points so that mechanically robust networks could be achieved. Driven by the reversibility of imine and disulfide bonds employed, the elastomers exhibited good self-healing property, and the healing efficiency reached up to 99% under ambient environments. Furthermore, the dynamic reversibility of the polymers was investigated at the molecular level. The imine and disulfide bonds were incorporated into the networks to construct a soluble and recyclable hyperbranched polymer with pH and redox responsiveness via an A(2) + B-3 approach and Schiff base polymerization. The polymers containing imine bonds completed the polymerization-depolymerization transition and underwent reversible cycles several times through changing pH. Moreover, in the presence of disulfide bonds, the polymers were provided with a redox cleavage property triggered by dithiothreitol. This study provides new opportunities for the design and application of intelligent polymers with tough networks through regulation of topological structures. |
