A supramolecular polymer gel is formed by host‐guest interactions between a DB24C8‐based bis(crown ether) and a copolymer containing the dibenzylammonium moiety. The formation of the gel and its cross‐linked networks structure are evidenced by 1 H NMR spectroscopy, viscometry, and SEM. Interestingly, the gel shows both pH‐ and thermoesponsive behaviors, and excellent self‐healing properties. The self‐healing property of the gel is tested by rheological measurements, and it can also be seen visually and directly. The presented work provides a new strategy for the construction of the self‐healing supramolecular polymer gels with potential applications in smart materials.
