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 nanocomposites obtained by simple solution intercalation and intercalation of chitosan and its derivatives into the nanostructures of layered silicates. The material is coupled with the synergistic advantages of chitosan and its derivatives and phyllosilicate, which opens up new directions and new ways for the research and development of chitosan. Based on a brief introduction of the properties and applications of chitosan and phyllosilicate, the preparation methods, intercalation mechanism and application status of chitosan-based phyllosilicate nanocomposites are reviewed. The main problem that exists at present.
