摘　　要：采用苯乙烯-丙烯腈共聚(AS)树脂对纳米石墨薄片(GN)进行包裹改性,制备成GN母料,并将它与高密度聚乙烯(HDPE)树脂进行混合挤出,制备了HDPE/GN复合材料,其渗滤阀值质量含量为14%。讨论分析了复合体系在加工过程中导电性能及其变化特征,研究了所制备的复合材料力学性能与石墨含量的关系。Graphite nanosheets were modified with acrylonitrile-styrene copolymer （AS resin ） to make GN masterbatch. The as prepared GN masterbatch was blended with high density polyethylene （HDPE） to prepare HDPE/GN nanocomposite. The percolation threshold of prepared HDPE/GN was about 14% of GN. The effect of extrusion times on the dispersion of GN and the electrical characteristies were discussed. The mechanical properties of the composites were also investigated.
