Rubbers exhibit enormous extensibility up to several hundred per cent, compared with a few per cent for ordinary solids, and have the ability to recover their original shape and dimensions on release of stress. Rubber elasticity is a property of macromolecules that are either covalently cross-linked or connected in a network by physical associations such as small glassy or crystalline domains, ionic aggregates or multiple hydrogen bonds. Covalent cross-links or strong physical associations… 
Activation and deactivation of self-healing in supramolecular rubbers
A remarkable self-healing property has been achieved recently with rubbers formed by a supramolecular network of oligomers. Here we explore this property through a tack-like experiment where two
Mechanically robust, readily repairable polymers via tailored noncovalent cross-linking
It is reported that low-molecular-weight polymers, when cross-linked by dense hydrogen bonds, yield mechanically robust yet readily repairable materials, despite their extremely slow diffusion dynamics.
