光交联法合成新型温敏性水凝胶的研究

Study on the Synthesis of β-HPAT-Cinnamic Oxygenmethyl Acrylamide(CMMAM) Thermoresponsive Hydrogel by Photocrosslinking

合成了丙烯酸 β 羟基丙酯(β HPAT) N 肉桂酰氧甲基丙烯酰胺(CMMAM)共聚物,采用光交联法制备了温敏性共聚水凝胶。实验结果表明:共聚物交联程度随光照时间延长而增大;在一定温度范围内,水凝胶的溶胀率(SR)随温度升高而减小,表现出显著的温敏行为。

The hydrogel copolymers of βhydropropyl acrylatenNcinnamic oxygenmethyl acrylamide was produced with photocrosslinking. The experiments show that the photocrosslinking extent of the copolymers will increases with increasing the time of the UV's shining. After observing the expand rate of hydrogel,it turns out that the hydrogel expansiveness will decrease with the increase of the temperature within a certain extent and it has the remarkable thermoresponsive.
