In Situ Construction of High Strength Chitosan/Polydopamine Hydrogel in Alkali System with Potential Radical Scavenging and Bacterial Inhibition
Herein, a novel chitosan-polydopamine hydrogel was constructed through the in situ self-polymerization of dopamine in a chitosan/alkali aqueous solution. Solid-state 13C NMR, FTIR, and SEM confirmed that the formed polydopamine (PDA) particles easily wrapped on chitosan chains to fabricate homogeneous porous hydrogels...
