Self-repairing property of polymer network with dangling chains

A new type of self-repairing polymer was proposed by utilizing strong topological interaction of dangling chains in the network polymer that was obtained by eliminating sol-fraction in a weak gel just beyond sol–gel transition point.

Zusammenfassung:A new type of self-repairing polymer was proposed by utilizing strong topological interaction of dangling chains in the network polymer that was obtained by eliminating sol-fraction in a weak gel just beyond sol–gel transition point. It was confirmed that an applied cleavage by a razor blade was healed at room temperature without any manual intervention.
