摘要: The multi-walled carbon nanotubes (MWCNTs) /ferriferous oxide (Fe3O4) nano-composites have important research value in electromagnetic wave absorbing. Firstly, MWCNTs and nano-Fe3O4 particles were ball-milled by a ball mill to obtain Fe3O4/MWCNTs nanocomposites. The Fe3O4/MWCNTs nanocomposites were characterized by XRD, TEM and network vector analyzer. Finally, a model of microwave attenuation mechanism for Fe3O4/MWCNTs nanocomposites was established. The reflectivity of Fe3O4/MWCNTs nanocomposites was calculated and compared with the transmission model of electromagnetic wave incident vertically into Fe3O4/MWCNTs powder in free space random dispersion space. The results of the two models are almost identical, which provide a reference for predicting the microwave absorbing properties of Fe3O4/MWCNTs nanocomposites.
