Supramolecular hydrogel of poly(vinyl alcohol)/chitosan: A dual cross-link design

Supramolecular hydrogels are increasingly fascinating soft polymeric materials formed by noncovalent interactions. Poly(vinyl alcohol) ( PVA ), chitosan and graphite oxide ( GO ), good biocompatibility, and nontoxicity, are green materials with potential applications in biomaterials. Herein, a dual cross‐link supramolecular hydrogel of PVA /chitosan in the presence of GO was prepared. Without addition of any organic cross‐linker, the...
