传统磁性吸波材料Fe_3O_4,存在密度大,吸波范围较窄等缺陷;而碳家族的新成员-石墨烯,具有轻质、高比表面积、独特的物理、电学、磁学、力学性能等,成为优异的基体承载材料。本文制备Fe_3O_4纳米粒子以及石墨烯承载Fe_3O_4纳米颗粒复合材料,探索各个原料添加量对纳米颗粒形貌的影响,并研究不同纳米颗粒承载量的复合材料的微观结构变化以及对吸波性能的影响。
The traditional magnetic absorbing material Fe 3 O 4 has the disadvantages of large density and narrow absorbing range. The new member of the carbon family, graphene, has the advantages of light weight, high specific surface area, unique physical, electrical, magnetic and mechanical properties, Become excellent substrate carrier material. In this paper, Fe_3O_4 nanoparticles and graphene supported Fe_3O_4 nanoparticle composites were prepared to investigate the influence of the amount of each raw material on the morphology of the nanoparticles. The microstructural changes of the composites with different nanoparticle loadings and their influence on the microwave absorbing properties were investigated.
