聚合物/粘土纳米复合材料中有机改性剂的研究进展

Progress of the Organic Modifiers in Polymer/Clay Nanocomposites

粘土的有机化改性是制备聚合物/粘土纳米复合材料的关键步骤。文中综述了近年来此领域的最新研究进展,详细介绍了不同有机铵盐、多功能引发剂和功能化插层剂作为改性剂的情况,以及粘土接枝改性和低聚物相容剂改性的效果。重点介绍了新型有机改性剂的组成、结构、性质、改性机理及改性后纳米复合材料的性能和应用。最后总结了改性剂设计和使用的研究方向。

Organic modification of clay is the key process in preparation of polymer-clay nanocomposites （PCN）. This paper reviewed the recent research progress and development in this field. Firstly,we presented the effect of different ammonium salts and multi-functional initiators,as well as functional intercalating agents as modifiers. Then edge grafting of clay and modification with oligomer compatibilizers were introduced briefly. Most attention was focused on the introduction of composition,structure,properties of organic modifiers and mechanism of the modification process in this review. In addition,applications of some newly developed PCN,and the prospects in design and application of the organic modifiers were discussed.
