25_20i/2013Hydrogels: Preorganized Hydrogel: Self-Healing Properties of Supramolecular Hydrogels Formed by Polymerization of Host–Guest-Monomers that Contain Cyclodextrins and Hydrophobic Guest Groups (Adv. Mater. 20/2013)

Generally, damaged polymeric materials do not return to their original shape and strength. If the damaged materials can recover spontaneously, material consumption can be minimized. Polymeric materials cross-linked with a hostguest interaction successfully showed a selfhealing property, as reported by Akira Harada and co-workers on page 2849. The authors choose cyclodextrin-host and hydrocarbon guest moieties to obtain self-healing materials. When cutting the material, cooperative host–guest complexation on the cut surfaces should effectively adhere to each other and recover the material strength.
