摘要
采用纳米石墨微片(GNP)为导电填料与线形低密度聚乙烯(PE-LLD)共混来制备导电复合材料,研究了改变GNP、表面处理剂十二烷基苯磺酸钠(SDBS)和分散剂聚乙二醇(PEG)的添加量对导电复合材料的力学性能、导电性能和热性能的影响。结果表明,GNP添加量为40份时,材料会形成导电网络,体积电阻率达到8.95×10~8Ω·cm,继续增加GNP的添加量对材料的导电性能和力学性能影响不大;导电复合材料的最佳配方为:100份PE-LLD、40份GNP、SDBS和PEG均为GNP质量的10%。
Conductive PE-LLD plastics was prepared by blending with graphite nano-platelet(GNP).The effect of GNP,surfactant sodium dodecyl benzene sulfonate(SDBS),and dispersant polyethylene glycol(PEG) on the mechanical and conductive properties was investigated.It was found that when the loading of GNP was 40%,a conductive network was formed,the electrical resistivity reached 8.95×10~8 Ω· cm.The optimal recipe was found as PE-LLD 100 phr,GNP40 phr,SDBS and PEG 4 parts.
