摘　　要：综述了聚乙烯 粘土纳米复合材料的制备方法及性能。熔融混合和原位聚合两种方法可用以制备插层或剥离态的纳米复合材料。粘土物质在聚乙烯基体中的良好分散提高了材料的强度 ,并使其具有阻燃性和气体阻隔性。The synthetic routes and materials properties of polyethylene/clay nanocomposites are reviewed. Intercalated or exfoliated nanocomposites can be prepared by melt-intercalation and in-situ coordination polymerization. The well dispersion of nanoscale inorganic fillers in polyethylene matrix promotes several properties of the material including improved stiffness,increased flame retardancy and better gas barrier property.
