Thermoresponsive Hydrogels Reinforced with Supramolecular Cellulose Filler

Thermoresponsive poly(N-isopropylacrylamide) hydrogels reinforced with supramolecular cellulose fibers were fabricated. Adamantane was immobilized on the surface of the cellulose fibers, and β-cyclodextrin was introduced into the hydrogel matrix. The interfacial host–guest interaction between the filler and the matrix effectively enhanced the mechanical strength of the hydrogels both in the swelling and deswelling states.
