【摘要】 传统磁性吸波材料Fe₃O₄,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Fe₃O₄纳米粒子以及石墨烯承载Fe₃O₄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。更多还原

【Abstract】 As a traditional absorbiong material Fe₃O₄ has large density and narrow absorbing range.On the other hand,graphene has outstanding properties and large specific surface area which become an ideal candidate of the base materials.In this paper,Fe₃O₄ nanoparticles and graphene bearing Fe₃O₄ nanoparticles with different mass ratio were obtained by solvothermal method.The absorption properties and the connection between the structure and performance were studied.更多还原
