        High-Frequency Absorption of the Hybrid Composites with Spindle-like Fe3O4 Nanoparticles and Multiwalled Carbon Nanotubes

        Ruozhou Xia,Yichao Yin,Min Zeng,Hangrong Dong,Haozhe Yang,Xiaojun Zeng,Wukui Tang,Ronghai Yu 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2016 NANO Vol.11 No.9

        The anisotropic spindle-like Fe3O4 hybrid nanocomposites blended with multi-wall carbon nanotubes (MWCNTs) have been prepared to function as an ideal lightweight candidate for electromagnetic (EM) wave absorption with decent performance in high frequency. The microstructure, morphology, magnetic properties, charge-transfer behavior and EM wave absorbing performance have been characterized by powder X-ray diffractometer, transmission electron microscope, vibrating sample magnetometer, Raman spectrometer and vector network analyzer, respectively. A maximum reflection loss reaches around -40 dB with 5% MWCNTs loading density. Compared with the monomer Fe3O4, the complex permittivity and permeability of the Fe3O4–MWCNTs nanocomposites are kept in balance, achieving a better impedance matching with a larger dielectric loss and magnetic loss. The optimization may be attributed to the synergistic effect between spindle-like Fe3O4 nanoparticles and MWCNTs. Moreover, the EM microwave absorbing performance can be optimized by tuning the Fe3O4–MWCNTs mass ratio and layer thickness of the samples, indicating promising application prospects for outstanding performance EM attenuation materials in high frequency.
