英文摘要	以聚偏氟乙烯(PVDF)树脂为基材,采用共辐射接枝方法,在PVDF树脂上接枝苯乙烯(St)/甲基丙烯酸二甲氨基乙酯(DMAEMA)二元单体,随后对接枝产物进行磺化和质子化反应引入磺酸基和叔氨基正离子得到了一种新型的PVDF基两性离子交换树脂.红外光谱、X射线光电子能谱(XPS)、热重和扫描电镜(SEM)分析证明了辐射引发接枝共聚及功能化反应的成功进行.接枝反应条件如溶剂、剂量和二元单体浓度对接枝率(GY)有明显的影响.随着接枝率的增加,功能树脂的离子交换容量随之增大,但接枝链St与DMAEMA的摩尔比不变,其阳离子及阴离子交换容量最大分别可达2.16 mmol/g,1.06 mmol/g.; A novel amphoteric ion exchange resin was prepared by radiation-induced grafting styrene (St) and dimethylaminoethyl methacrylate (DMAEMA) onto the poly (vinylidene fluoride) resin, followed by sulfonation and protonation processes. Micro-FTIR, XPS, TG and SEM analyses testified that the grafting and sulfonation of St and DMAEMA units in poly (St-co-DMAEMA) grafts had been carried out successfully as designed. The grafting yield (GY) was greatly influenced by the grafting conditions including the solvent, the total absorbed dose and the monomer concentration,while the composition of the graft chains only depends on the initial molar ratio of St and DMAEMA. The ion exchange capacities (IEC) increases with the increasing of GY,and eventually the maximum cation and anion exchange capacities can reach to 2.16 mmol/g and 1.06 mmol/g, respectively. This type of new ion exchange resin can be used in treatment of heavy metal waste water and as ion exchange membrane material.; 国家自然科学基金; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 11; 1276-1282
