文章综述了一类新型潜在阻燃高分子材料--聚合物/无机物纳米复合材料。简述了这类材料的特征及制备方法，详述了PPgMA（顺丁烯二酸酐接枝聚丙烯）/LS（层状硅酸盐）及PS/LS两种纳米复合材料的阻燃性能，并讨论了材料结构与阻燃性的关系。

A novel potential flame-retarded polymeric material——olymer/inorganics nanocomposite is reviewed. The characteristics and preparation methods of this kind of material are briefly described. The flame retardancies of both PPgMA (polypropylene graft maleic anhydride) /LS (layered silicate) and PS/LS nanocomposites are summarized in detail, and the effects of structures of PS/LS nanocomposites on material´s flame retardancy are discussed.
