Preorganized Hydrogel: Self-Healing Properties of Supramolecular Hydrogels Formed by Polymerization of Host-Guest-Monomers that Contain Cyclodextrins and Hydrophobic Guest Groups

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...

Zusammenfassung:	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.
