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。
Nano-graphite flake (GN) was modified with styrene-acrylonitrile copolymer (AS) resin to prepare GN masterbatch, and mixed with high-density polyethylene (HDPE) GN composites, the percolation threshold mass content of 14%. The conductive properties and the changing characteristics of the composites during processing were discussed. The relationship between mechanical properties and graphite content of the prepared composites was also studied.
