摘要
针对亲水性海藻酸钠微胶囊的应用局限,总结了4种海藻酸钠疏水改性方法,即酯化法、酰胺化法、开环氧化法、接枝共聚法;介绍了4种方法的新进展并比较了各种方法的优缺点,指出其作为新型材料可拓宽在化工、环保等领域的工业化应用。
In view of the limitation of hydrophilic sodium alginate microcapsules, the hydrophobic modification of alginate is raised. Four kinds of hydrophobic modification methods, that is, esterification, amidation, openring oxi- dation, and graft copolymerization, are summarized. The progress of the four methods are introduced, and the advan- tages and disadvantages are compared. Finally, it is proposed to broaden the application of hydrophobically modified alginate into chemical industry and environment protection.
