The high density, cost, and environmental pollution hinder the application of iron-based electromagnetic wave-absorbing materials. Although bio-carbon is a green lightweight dielectric material, performance still limited. This work successfully combined magnetite Fe3O4 with porous carbon derived from spinach stem using hydrothermal calcination methods. process optimizes matching constant magnetoconductivity as prepared composite resulting in significant improvement microwave absorption capacity. XRD, SEM, TEM, XPS, VSM EMW network analyzer are used to detect characterize samples. material shows excellent minimum reflection loss value -48.81 dB an efficacious bandwidth 4.73 GHz at optimal raw ratio. tests also show structure sample coercivity saturation magnetization 29.36 Oe 10.75 emu/g, respectively. test results indicate that wave due synergistic effect multiple reflection, Debye relaxation, interfacial polarization. Fe3O4-bio-carbon cheap simple prepare, it has performance. Therefore, great potential civilian military fields.
