摘要

Poly(N

N-dimethylaminoethyl methacrylate) (polyDMAEMA) hydrogels prepared by γ-irradiation showed obvioustemperature-sensitivity in a temperature range of 38-40℃ and pH-sensitivity at pH = 2.5. They also showed clectric responsebehavior although it was not typical. The hydrogels were used in controlled release at different pH

temperature

and electricvoltage. The release rates of methylene blue (MB) from the gels at 52℃ and pH = 1.24 were fatter than those at 20℃ and pH= 10.56

respectively. In addition

the release rate at a field voltage of 5.0 was also faster than that without electric field.
