<\/p>\nHydrogels or plastics formed by using covalent bond, once ruptured or damaged, cannot be repaired to their original state without melting them in general. Moreover, conventional self-healing materials formed by using non-covalent bond don\u2019t have\u3000enough property for their insufficient combination strength although they can be recombined reversibly. Inventors have formed new self-healing polymers by incorporating host and guest molecules into the same polymer main chain and synthesizing them with using an unconventional technique. They can be self-healed any number of times by using host-guest interaction, without any stimulation at room temperature, when rupture surfaces are adhered to one another.<\/p>\n
1. Non-covalent cross-links are unbound when ruptured The polymers of this technology are cross-linked non-covalently by using host-guest interaction (ex. Cyclodextrin and Alkyl group). When they are ruptured, mainly these cross-links are unbound. So, when the rupture surfaces are adhered to one another, they are self-healed up to their original strength.<\/p>\n
2. Selective self-healing between rupture surfaces Rupture surfaces are not adhered to non-rupture surfaces. Rupture surfaces and damage surfaces are self-healed selectively without unnecessary adhesions.<\/p>\n
