What is Multi-carbon Encapsulating Soft-magnetic Nanocomposite with Environmentally Adaptive Wideband Electromagnetic Wave Absorption about?
High-performance composite electromagnetic microwave (EM) absorbers are required to have good environmental adaptability, especially in corrosive environments. Multiple carbon coated FeNi (MCFN) magnetic nanocapsules assembled by liquid-phase electrostatic adsorption are presented as an anticorrosive microwave absorber. Compared to previously reported EM absorber of graphite coated FeNi nanocapsules, present nanocapsules modified by Polyvinyl alcohol (PVA) with subsequent annealed arrangement achieve the enhanced broadband EM absorption due to enhanced impedance matching and increased electric dipoles, which are related to the multiple interfaces between different carbon capsulations. The optimal 50 wt% MCFN filled in paraffin shows a minimum reflection loss (RL) -63.26 dB at 11.45 GHz with a thickness of 2.9 mm and 6.57 GHz (RL < -10 dB) absorbing bandwidth with thickness of 2.5 mm. The MCFN microwave absorber coating exhibits long-term corrosion resistance due to the synergistic effect of the chloridion-capture capacity of the multi-layer interface and dual corrosion resistance. After soaking for 30 days NaCl solution, the |Z| 0.01 Hz value of the MCFN coating remains at a high l
