swelling behaviour of hydrogel nanocomposites based on carboxymethyl cellulose

in this work, swelling behaviour of a novel hydrogel nanocomposite based on carboxymethyl cellulose (cmc) was reported. firstly, the hydrogel nanocomposite was synthesized via a simple solution graft copolymerization of acrylic acid (aa) and 2-acrylamido-2-methylpropanesulfonic acid (amps) monomers onto cmc in the presence of cds quantum dots by using ammonium persulfate as an initiator and methylene bisacrylamide as a crosslinker. then, the certain variables of the graft copolymerization (i.e. the monomers, the initiator, the crosslinker, cmc, cdcl₂, and na2s concentrations) affected on the ultimate water-swelling capacity were optimized in detail.
