Description
Summary:Severe electromagnetic (EM) interference pollution as the fourth pollution has posed an ever increasing threat to human health and environment. These dangers have created an urgent need for the development of EM absorbers to address this issue. Herein, nanosized NiO and Fe3O4 particles were decorated along multiwalled carbon nanotubes (MWCNT) to achieve high-performance attenuation of EM waves of 2–18 GHz and a power frequency of 50 Hz. The hybrid nanotubes were prepared by an electroless nickel plating-oxidization process to form MWCNT/NiO, then followed by a polyol approach to produce triple-component MWCNT/NiO-Fe3O4 hybrid nanotubes. The microstructure of the hybrid was characterized by transmission electron microscopy, X-ray diffraction and vector network analysis. It was found that the multi-component structure endows the MWCNT/NiO-Fe3O4 hybrid nanotubes with an effective EM absorption band (RL
