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.
