摘要
壳聚糖基层状硅酸盐纳米复合材料是采用简单的溶液插层法,将壳聚糖及其衍生物插层进入层状硅酸盐的纳米层间而获得的有机无机纳米杂化材料。该材料偶合了壳聚糖及其衍生物和层状硅酸盐的协同优势,为壳聚糖的研发应用开辟了新方向和新途径。本文在对壳聚糖和层状硅酸盐的特性及应用进行简单介绍的基础上,重点综述了壳聚糖基层状硅酸盐纳米复合材料的制备方法、插层机理及应用现状,并提出了目前存在的主要问题。
Chitosan-based layered silicate nanocomposites are organic-inorganic hybrid nanocomposites, with chitosan intercalated into the interlayer of layered silicate via simple solution intercalation method. Compared with the ordinary composites, they excel in the structure, form, property and applications. Intercalation of chitosan with layered silicate, identifying the biology characterisation of chitosan by layered silicate, combination the advantages of chitosan with layered silicates, and constructing novel chitosan nanocomposite from molecular level, opened up the new development directions for chitosan. This paper introduced the properties and applications of chitosan and layered silicate, summarized the intercalation method, mechanism and applications of chitosan-based layered silicate nanocomposites. Their existing problems are also mentioned.
