On the mechanism for the highly sensitive response of cellulose nanofiber hydrogels to the presence of ionic solutes

Hydrogels formed by cellulose nanofibers (CNFs) find use in a variety of applications. CNF hydrogels generally stiffen and ultimately flocculate with increasing salt concentrations. While charge repulsion explains the behavior of nanocellulose variants that have been stabilized by charged groups, it...
