文摘

Nano-TiO2/chitosan/poly(N-isopropylacrylamide) composite hydrogel was prepared by a two-step polymerization method. Nano-TiO2 was used to give the photocatalytic activity of the composite hydrogel. The composite hydrogel exhibited high efficiency of acid fuchsin dye removal rate under UV irradiation.
