以丙烯腈-丁二烯-苯乙烯共聚物(ABS)和聚偏氟乙烯(PVDF)为基体,不锈钢纤维(SSF)和石墨为导电填料,通过熔融法制备SSF-石墨/ABS-PVDF导电复合材料,探究了其导电性能及流变性能.讨论了SSF/ABS-PVDF复合体系中导电填料的分布、导电性能及基体的相转变行为.结果表明:SSF倾向于分布在PVDF相中,当SSF含量为20wt％时,SSF/ABS-PVDF复合材料的电阻率随PVDF比例增加,先降低经历一个平台期后继续降低.PVDF在ABS-PVDF复合基体中含量为30wt％～40wt％和70wt％～80wt％时,SSF/ABS-PVDF复合材料出现相态转变行为.当SSF含量为16.84wt％和25wt％～30wt％时SSF-石墨/ABS-PVDF复合材料出现二次逾渗的现象,且与其动态模量及复数黏度的变化相符合.
