Abstract:Swelling studies are essential for hydrogels with potential applications in biomedical areas, as the materials will be exposed to biological fluids. This study obtained composite hydrogels by physically cross-linked carboxymethyl cellulose (CMC) with GO. CMC is known to be non-toxic, non-allergenic, and possesses good biodegradability. To produce GO, a ‘greener’ modified Hummers’ method was first employed by removing the use of sodium nitrate in the oxidation process to avoid the generation of toxic NOx gases.… Show more
