摘要
采用有机改性的层状硅酸盐与聚丙烯／尼龙6通过熔融插层成功制备了剥离型纳米复合材料，并发现相容剂马来酸酐改性聚丙烯（MPP）的加入使材料具有良好的加工流变性能。采用X射线衍射（XRD）及正电子淹没寿命谱（PALS）等方法研究了材料的微观结构，结果表明，加入相容剂MPP后，材料的自由体积浓度显著降低，平均孔洞大小则略有增加，这与MPP与基体分子间较强的相互作用密切相关。
Nanocomposites were dramatically produced using organically modified montmorillonite and polypropylene/ polyamide 6. It is also found that the PP/PA6/MPP/DK1 system possesses good rheological property. The microstructure has been studied by X-ray diffraction （XRD） and positron annihilation lifetime spectroscopy （PALS）.
