壳聚糖的功能化改性及其生物医学等领域的应用是近年来备受人们关注的重要研究方向。文章研究了TEMPO-NaOCl-NaBr体系对不同形态壳聚糖的氧化过程及其产物的结构表征。发现NaOCl、NaOCl-NaBr、TEMPO-NaOCl和TEMPO-NaOCl-NaBr体系的氧化反应速率递增，溶胀态壳聚糖和壳聚糖纤维由于有着更高的可及度，TEMPO-NaOCl-NaBr体系对两者的氧化速率要高于颗粒状壳聚糖原料和甲壳质原料。FTIR和NMR研究表明，经TEMPO-NaOCl-NaBr体系氧化后，壳聚糖分子结构中%The functional modification of chitosan and its application in biomedical field have been considered as one of the most important research directions, which attracted much attention in recent years. In this contribution, the oxidation behavior of chitosan
