摘　　要：采用高密度聚乙烯膜(HDPE)预辐射接枝N-异丙基丙烯酰胺(NIPA)和丙烯酸(AAc),制备既具有温度敏感又具有pH敏感的水凝胶。着重研究了吸收剂量、剂量率、单体浓度、反应时间、接枝单体配比、溶剂等实验条件对接枝率的影响,测试了水凝胶的温度敏感性和pH敏感性。This experiment adopts preirradiation grafting of NIPA/AAc onto HDPE membrane to prepare a hydrogel of temperature sensitiveness and pH sensitiveness. The paper analyses the influence of absorbing dose, dose rate, monomer concentration, grafting time, solvent on grafting rate. The hydrogel nature of temperature sensitiveness and pH sensitiveness was tested.
