Graphene oxide/polyacrylamide/carboxymethyl cellulose sodium nanocomposite hydrogel with enhanced mechanical strength: preparation, characterization and the swelling behavior

Abstract

A ternary GO/PAM/CMC nanocomposite hydrogel was fabricated by introducing GO into PAM/CMC hydrogels followed by ionically crosslinking of Al³⁺. The compressive strength of the ternary hydrogel was dramatically enhanced with the incorporation of only 1.6 wt% GO sheets.
