Self-healing stimuli-responsive cellulose nanocrystal hydrogels

Carbohydrate Polymers, 2020
A facile and universal approach to prepare cellulose nanocrystal reinforced functional hydrogels is proposed. An organic solvent-free and eco-friendly method was adopted, where both the modification and polymerization were conducted in an aqueous solution. Cellulose nanocrystal (CNC) and sodium alginate (SA) were first oxidized under mild conditions to

Self-Healing Mussel-Inspired Multi-pH-Responsive Hydrogels

Biomacromolecules, 2013
Self-healing hydrogels can be made using either reversible covalent cross-links or coordination chemistry bonds. Here we present a multi-pH-responsive system inspired by the chemistry of blue mussel adhesive proteins. By attaching DOPA to an amine-functionalized polymer, a multiresponsive system is formed upon reaction with iron.
