摘要：
prepare a uniformly network structured stimulus-responsive copolymer, organic polyethylene imine (PEI), polyethylene glycol glycidyl ether (PEGO) and inorganic calcium phosphate oligomers (CPO) as precursors, were used to prepare the PEI-PEGO-CPO hydrogels. The structure and properties of the products were characterized using infrared, 1H NMR and swelling behavior tests. The influence of CPO on temperature and pH sensitivity of the hydrogels was systematically investigated. The hydrogels were switched at temperatures between 20 and 60 degrees C, pH values between 8 and 13. The results showed that the addition of CPO can effectively improve the temperature and pH responsive properties of the hydrogels. In addition, the hydrogels showed excellent reversibility for swelling-deswelling characteristics.
