摘要 合成了苯乙烯/马来酸酐共聚物接枝聚乙二醇400(PEG400)水凝胶。研究了环境pH、温度、离子强度对该凝胶溶涨性能的影响,并对凝胶的动态溶涨行为进行了分析。结果显示该水凝胶对环境pH、温度、离子强度等变化均作出体积相转变响应,表现出了智能高分子凝胶的特性。 Styrene/maleic anhydride copolymer-g-PEG400 hydrogels were synthesized and characterized by FT-IR. Influences of environmental pH value, temperature and ionic strength on swelling performance of the hydrogels were investigated. Especially, the dynamic swelling mechanism was studied. The result shows that these hydrogels can wake quick volume response to the changing of pH value, temperature and ionic strength, as some features of intelligent gel.
