摘　　要：在凹凸棒土表面吸附马来酸酐 (MAH)单体和过氧化二异丙苯 (DCP)引发剂 ,将处理过的凹凸棒土填充HDPE ,制备HDPE/凹凸棒土纳米复合材料。结果表明 ,纳米复合材料的拉伸和冲击性能都有所提高 ,其中冲击性能提高了 5 0 %左右 ;用FT IR ,XRD ,TEM等方法 ,对HDPE/凹凸棒土纳米复合材料的结构进行表征研究。MAH and DCP was attached on the surface of attapulgite.The modified attapulgite was filled into HDPE to prepare nanocomposites.In the course of processing, polymer coupling agent which improves dispersion of attapulgite might be formed.The mechanical properties of the nanocomposites was enhanced,especially the Izod impact strength was enhanced about 50 percent. The process of the modified attapulgite and the structure of the nanocomposites were investigated by FT-IR, XRD,TEM.
