摘要
以膨胀石墨为基体,用硝酸铁、碳酸铵等物质对其进行修饰,结合化学气相沉积工艺,原位制备出石墨烯/碳纳米管复合粉体材料;利用扫描电镜对复合粉体进行了表征。采用熔融混炼的方法制备PBT/石墨烯/碳纳米管复合材料并测试了其表面电阻。研究结果表明:该方法可以制备出性能优异的石墨烯/碳纳米管复合粉体材料,将该复合粉体加入到PBT中所制备的复合材料具有优良的电性能;当复合粉体加入量为5%时,PBT/石墨烯/碳纳米管复合材料的表面电阻可达到106Ω。
It has been explored for synthesizing in situ mixture powder of graphene platelet （NGP） and carbon nanotube （CNT） using expanded graphite（EG） as the catalyst support through CVD technology. The structures of the mixture powder were characterized by SE1VL PBT/graphene platelets/carbon nanotube composites were prepared by melt blending method and their resistance were measured. The results showed that the excellent performance of NGP/CNT mixture powder materials can be prepared by this method. PBT/graphene platelets/carbon nanotube com- posites have excellent electrical properties. When the weight fraction of mixture powder reached 5%, PBT/graphene platelets/carbon nanotube composites material surface resistance can be up to 10^6Ω.
