Even if nanofibrillated  cellulose and cellulose nanocrystals have excellent mechanical properties, it has proven to be subtle to transform them to advanced macroscopic mechanical properties. Biological materials utilize self-assemblies and sacrificial bonds to achieve exciting combinations of mechanical properties. Inspired by them we incorporate tailored supramolecular interactions in nanocellulose  compositions to allow tough materials with increased process zones ahead the crack tips as well as stiff hydrogels with ultrafast healing, which do not become passivated upon extended storage time, unlike previous self-healing hydrogels.
