Abstract:
Provided are supramolecular polypseudorotaxane hydrogel compositions and 3-D structures capable of reversible 3-D structural deformation which include (a) a solvent; (b) an at least partially linear polymer, where the polymer further comprises groups capable of covalent crosslinking between the polymers; (ii) at least one first macrocyclic ring which forms a pseudorotaxane with a polymer in the polymer network; and (iii) at least one second macrocyclic ring that does not form the pseudorotaxane. The hydrogel composition has a viscosity which allows for 3-D printing of the hydrogel to form a 3-D structure, and a storage (elastic) modulus after crosslinking that allows for the 3-D structure to undergo reversible 3-D structural deformation upon change of solvent conditions. Also provided are methods of manufacturing the compositions and 3-D structures.
