摘要 甲壳素是一种天然多糖,脱除乙酰基的产物是壳聚糖,作为新型功能生物材料,它们已在水处理、日用化学品、生物工程和医药等领域得到了应用,但它们不溶于一般的有机溶剂,从而限制了其广泛应用。为此,甲壳素和壳聚糖的化学改性成为该材料研究的重要方向之一。本文综述了近年来甲壳素和壳聚糖化学改性方面的研究进展,着重介绍了选择性化学修饰的方法和发展动向。 Chitosan,an amino polysaccharide obtained by deacetylation of chitin is the most abundant natural resources and widely distributed in the cuticle of the Crustacea. Recently chitin and chitosan have become of great interest not only as biopolymers, but also as a new functional materials of high potential in various fields ranging from a simple floccule for waste water treatment to medical materials such as for wound healing and prevention of infection. This review has a closer look at chemical modification of chitin and chitosan. Based on current research and existing products, some new and futuristic approaches in this fascinating area are thoroughly discussed.
