摘　　要：以过氧化二异丙苯(DCP)为引发剂、乙烯基三乙氧基硅烷(VTES)为交联剂,对高密度聚乙烯(HDPE)进行化学交联改性。结果表明:功能化石墨烯(KRGO)与交联结构对HDPE抗静电性能具有协同作用。KRGO质量份为3份时,通过提高HDPE交联度可以促进石墨烯导电通路的形成,KRGO/HDPE复合材料产生良好抗静电性能。当交联度为40.00%~50.00%时,类渗流区域出现;当交联度为49.43%时,KRGO/HDPE复合材料体积电阻率可降至10^(9)Ω·cm。High density polyethylene(HDPE)was chemically crosslinked with dioctyl phthalate(DCP)as initiator and vinyl triethoxysilane(VTES)as crosslinking agent.The results show that functionalized graphene(KRGO)and crosslinking structures have synergistic effect on the antistatic properties of HDPE.When the mass fraction of KRGO is 3phr,the formation of graphene conductive path can be promoted by increasing the crosslinking degree of HDPE,and KRGO/HDPE composites exhibit excellent antistatic properties.When the crosslinking degree is between 40%and 50%,similar seepage zone appears.When the crosslinking degree is 49.43%,the volume resistivity of KRGO/HDP composites can be reduced to 10^(9)Ω·cm.
