Superior Impact-Resistant Composite Hydrogels Through an Ionic Coupling Strategy. [PDF]
Adv MaterAn ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,
