摘要
从层状硅酸盐的微观结构及其与聚合物插层时的热力学理论两方面概述了聚合物/层状硅酸盐(PLS)纳米复合材料制备的可行性及层状硅酸盐的修饰方法。介绍了纳米硅酸盐在聚合物熔体中的分散理论及达到纳米分散的关键技术。对该复合材料的微观结构、烧蚀机理及烧蚀性能表征测试方法进行了说明,并指出其在火箭发动机内绝热材料中的应用前景。附参考文献22篇。
Based on the microstructure of layer-silicates and the theory of thermodynamics when intercatated polymer into layer silicate, the feasibility of preparing polymer/layered silicate nanocomposites and the modified methods of layer silicates were discussed. The theory of dispersion of nanosilicate in polymer melt and the key technique to reach nanoscale dispersion were introduced. The characterization and test method of microstructure, ablative mechanism and ablative properties of the composites were specialized and application prospects in rocket engine motor inner insulation were pointed out with 22 references.
