摘　　要：通过加入适量马来酸酐接枝聚乙烯(PE-g-MAH),用熔融插层法制备了聚乙烯(PE)／蒙脱土(MMT)纳米复合材料,采用X射线衍射(XRD)、透射电镜(TEM)等表征了复合材料的微观结构和形态。结果表明聚乙烯分子链已插入蒙脱土片层间,实现了插层复合。复合材料热稳定性和对气液阻透性的测定结果表明,与基体聚乙烯相比,复合材料的热分解温度有所提高,对有机溶剂及气体的阻性也有较大改善。Polyethylene（PE）/montmorillonite（MMT） nanocomposites were prepared through melt intercalation using maleic anhydride modified PE （PE-g-MAH） as a compatibilizer. The microstructure and morphology of the composites were characterized by X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The characterization indicated that the PE chains had intercalated into the layer of MMT. The influence of PE-g-MAH was studied. The thermal decomposition temperature of composites was enhanced, and the barrier properties against organic solvent and vapor were improved significantly compared with neat PE.
