Supramolecular hydrogels formed by a host-guest interaction show self-healing properties. The cube-shaped hydrogels with β-cyclodextrin and adamantane guest molecules mend after being broken. The hydrogels sufficiently heal to form a single gel, and the initial strength is restored. Although contact between a freshly cut and uncut surface does not mend the gels, two freshly cut surfaces selectively mend.
超分子水凝胶通过主客体相互作用形成，表现出自愈特性。具有β-环糊精和金刚烷客体分子的立方体形水凝胶在破裂后能够自我修复。水凝胶充分愈合后形成单个凝胶，初始强度得以恢复。虽然新鲜切割面和未切割面之间的接触不会使凝胶愈合，但两个新鲜切割面可以选择性地愈合。
