“…However, the dynamic phenol–carbamate bonds are thermally unstable, which can be dissociated and recombined at a certain temperature. 56–59 Furthermore, the reversible exchange of the phenol–carbamate bond has also been confirmed in our previous studies, 24,25,60,61 and according to the relevant literature, the catechol–Fe 3+ cross-links are also reversible, 62,63 which may make the TAPU/Fe-4 polymer recyclable and reusable. As shown in Fig.…”

“…23 In our previous work, TA was incorporated into the polyurethane skeleton to form a cross-linked phenolcarbamate network, which can undergo dynamic exchange at a certain temperature. 24,25 Therefore, we speculated that the combination of the excellent photothermal performance of the Fe 3+ /TA complex and the ideal dynamic exchange of the phenolcarbamate network in a thermosensitive polyurethane hydrogel comprising PEG/PPG (polypropylene glycol) blocks will endow it with the desired NIR light responsiveness, good mechanical properties, and reprocessing ability. As far as we are aware, there is no report yet on the fabrication of multifunctional polyurethane hydrogels in a synergistic manner wherein TA serves as a bridge to construct the phenol-carbamate network and Fe 3+ -polyphenol coordination network.…”

Polyurethane (PU) is a polymer with great capabilities like high elasticity, low-temperature resistance, wear resistance, and corrosion resistance. However, it will inevitably be damaged in processing or long-term use, which will shorten the service life of the material and increase the potential safety hazards. The widespread use of polyurethanes has given researchers more motivation to make polyurethanes self-healing, thereby eliminating material damage and potential safety hazards to a certain extent. This paper mainly reviews the self-healing mechanism and the research progress of intrinsic self-healing polyurethanes based on dynamic reversible non-covalent bonds, including H-bonding, metal-ligand, π-π and host-guest interactions. This paper holds that the non-covalent self-healing polyurethane can repair cracks repeatedly without adding a repair agent by introducing the above non-covalent reversible bonds into the polyurethane with good mechanical properties. Various types of reversible bonds provide a variety of options for self-healing. In addition, through the research on the preparation, mechanical properties, and self-healing ability of various self-healing polyurethanes, this paper summarizes and analyzes the prospect and existing problems of self-healing polyurethanes. In the future, researchers should focus on solving the existing deficiencies. This paper looks forward to finding a better scheme to improve the performance of self-healing polyurethanes and preparing ideal self-healing polyurethane materials that appear in the public’s field of vision. This paper is written to provide help for the research of self-healing PU and accelerate the transformation of the world to green development.
