The effects of monomer content, pH and temperature on swelling ratio of the hydrogel were investigated; the thermo-sensitivity in deionized water and in physiological saline was determined. It showed that the swelling ratio of the hydrogel could be changed by changing the temperature or pH alternately. Both swelling ratio and LCST (Lower Critical Solution Temperature) of the hydrogel decreased with the increase of NIPAAm in the co-polymer content.展开更多
