fabrication of self-healing hydrogels through inclusion complexation of vinyl modified macrocyclic monomers

The development of self-healing materials with the ability to repair damage has received considerable attention.  cyclodextrin (cd)-based host–guest interactions are one of the important supramolecular interactions and have been playing significant role in the design of self-healing materials due to high selectivity and dynamic equilibrium. we employed radical polymerization of  host–guest inclusion complexes of β-cyclodextrin (β-cd) and adamantane (ad) with 2-hydroxyethyl methacrylate (hema), acrylamide (aam) to form a supramolecular hydrogel (β-cd-ad gel). β-cd-ad gel displayed good self-healing ability, and could effectively heal in a few seconds.
