Abstract: 旨在为降低吸水材料成本、拓宽原料来源、提高生物降解性、减少对石油化工产品的依赖提供指导,以水溶液接枝共聚法制备了淀粉接枝衣康酸/丙烯酸高吸水材料(S/IA/AA),讨论了淀粉糊化条件、中和度、单体含量、反应温度等因素对材料吸水性能的影响,采用FTIR、SEM、EDX等对吸水材料进行表征。研究表明:淀粉糊化最佳条件为糊化温度80℃,糊化比为10g·g-1,糊化时间30min;吸水材料合成最佳条件为中和度50%,衣康酸40%,淀粉20%,引发剂为4×10-3mol·L-1,交联剂0.075%,反应温度50℃;利用40%衣康酸替代丙烯酸所制S/IA/AA同S/AA相比,其吸水性能有一定提高且保水性能优良。
