SWELLING BEHAVIOUR OF HYDROGEL NANOCOMPOSITES BASED ON CARBOXYMETHYL CELLULOSE

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.
