传统可降解高吸水材料的研究

Studies on Traditional Biodegradable Super Absorbent Material

可降解高吸水树脂是一种良好的吸水、保水材料,自研发以来,广泛应用于医药、农业和化工行业。本文主要综述了可降解高吸水材料早期的研究,包括丝素蛋白水凝胶类、淀粉类、纤维素类、海藻酸钠类和其他天然高分子类、聚乳酸和聚氨基酸类,介绍了可降解高吸水树脂的性质、传统合成工艺、反应原理,和其他原材料加入对复合吸水树脂综合性能的影响。

Biodegradable super absorbent polymer, a kind of good water absorbent and water retaining material, has been widely used in medicine, agriculture and chemical industry since its research and development. In this paper, the early studies of biodegradable super absorbent materials were reviewed, including silk fibroin hydrogel, starch, cellulose, sodium alginate and other natural polymers, polylactic acid and poly(amino acids). Also, the properties, traditional synthetic technology, synthetic principle of super absorbent polymer and the influence of adding other materials into composite super absorbent material were introduced.
