Deswelling Behaviors of Poly(N-isopropylacrylamide)/Carboxymethylchitosan/ Clay Nanocomposite Hydrogel

摘要

The poly(N-isopropylacrylamide) / carboxymethylchitosan/clay nanocomposite hydrogels were prepared, whereas inorganic clay acted as a crosslinker. The hydrogels displayed an obviously rapid response in deswelling when compared to the conventional hydrogels cross-linked by chemical reagent (usually N, N'-methylenebisacrylamide). The rate of deswelling increased when the content of CMCS increased or the content of clay lowered.
