Thermoresponsive Hydrogels Reinforced with Supramolecular Cellulose Filler

Abstract

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.

Exploring Applications and Preparation Techniques for Cellulose Hydrogels: A Comprehensive Review

“…Cellulose consists of long-chain polysaccharides composed of β-D-glucose units ( Figure 1 a), interconnected through β-(1→4)-glycosidic bonds( Figure 1 b). The presence of these β-glycosidic bonds makes cellulose insoluble in water [ 53 ], a property essential for its stability and utility. The fundamental repeating unit within cellulose molecules, known as cellobiose, forms linear polymer chains.…”

Cellulose‐based Conductive Gels and Their Applications

“…By utilizing the intrinsic properties of cellulose and the chemical modification of cellulose, multi-stimuli-responsive actuators using conductive cellulose gels could be obtained. [149] Jeon et al prepared conductive organogels by integrating cellulose and PEDOT : PSS in tripropylene glycol. [150] Because cellulose gels have different degrees of swelling in various solvents due to the hydrogen bonding interactions between the solvent and cellulose chains, the bilayer gels consisting of a thick isotropic layer and a thin anisotropic layer can significantly vary in response to changes in swelling in different solvents (Figures 7(a)-7(d)).…”
