摘　　要：以铁离子、碳纳米管、氧化石墨烯为原料,经过硫化铵或多巴胺还原、氨水增强的共沉淀法制备四氧化三铁/碳纳米管/石墨烯(Fe_(3)O_(4)/CNT/G)粉体,再将粉末添加到天然胶乳中用流延法制备成复合材料。通过X射线衍射仪(XRD)、扫描电镜(SEM)、振动样品磁强计(VSM)、拉伸测试仪等表征方法研究了Fe_(3)O_(4)/CNT/G天然胶乳复合材料的结构和力学性能、导电、导磁性能。结果表明:硫化铵工艺制备出来的粉末的导电性和导磁性都要优于多巴胺工艺制备出来的粉末(电导率为0.21S/mm;饱和磁化强度和矫顽力为14.01emu/g和4.11Oe)。当复合材料中Fe_(3)O_(4)/CNT/G粉末添加量为3%时,力学性能达到最佳,拉伸强度为9.8MPa。The Fe_(3)O_(4)/carbon nanotube/graphene powders were prepared by ammonium sulfide or dopamine reduction and ammonia-enhanced coprecipitation method from iron ions,carbon nanotubes and graphene oxide,then the powders were added into the natural latex and the composite was prepared by casting method.The structure,mechanical properties,electrical and magnetic conductivity of Fe_(3)O_(4)/carbon nanotube/graphene composites were studied by means of X-ray diffraction(XRD),scanning electron microscopy(SEM),magnetic conductivity(VSM)and tensile tester.The results showed that the electrical and magnetic conductivity of the powder prepared by the ammonium sulphide process were better than that of the powder prepared by the dopamine process(electrical conductivity of 0.21S/mm;saturation magnetization and coercive force of 14.01emu/g and 4.11Oe).When the powder content of the composite was 3%,the mechanical properties achieved the best,with a tensile property of 9.8MPa.
