介绍了一种新型电磁功能材料.该材料由表面无电子镀镍的空心微球组成.采用扫瞄电镜观测了镀镍前后的表面微观结构,制备成样品放入X波段波导框中,在微波网络分析仪上进行散射参数测量,计算了电磁特性参数.结果表明,该材料在表面镀镍后取得了较高的磁导率(19.0)和磁损耗正切(0.6),而介电常数保持较低(1.8).与非金属化微球材料相比,可作为超薄型多层微波吸收材料的基本材料. A new kind of electromagnetic functional material is introduced, which is composed of hollow microspheres without electroless nickel plating on the surface.The microstructure of the surface before and after nickel plating was observed by scanning electron microscope, and the sample was prepared into X - The results show that the material has higher magnetic permeability (19.0) and magnetic loss tangent (0.6) after nickel plating on the surface, while the dielectric constant is maintained relatively Low (1.8). Compared with non-metallic microspheres material, can be used as a basic material for ultrathin multilayer microwave absorbing material.
