Composite hydrogels with host–guest interaction using cellulose nanocrystal as supramolecular filler

A quadruple-stimuli responsive supramolecular hydrogel constructed from a poly(acrylic acid) derivative and β-cyclodextrin dimer

“…13–17 Unfortunately, multi-responsive hydrogels are still rare, which is due to the limited availability of techniques to produce architectures with complex inherent sensitivity properties. 18–21…”
