Abstract
The C@CIPs absorbents were fabricated by the mechanical milling method. The particle morphology and crystal grain structure were characterized by the scanning electron microscopy and the X-ray diffraction patterns, respectively. The complex permittivity and permeability of the absorbing composites added the hybrid particles were tested in 2–18 GHz. The reflection loss (RL) and shielding effectiveness were calculated using the tested parameters. It was found that the MWCNTs were bonded to the CIPs surface. The permittivity and permeability of the C@CIPs were increased as the MWCNTs coated on the CIPs. It was attributed to the dielectric property of MWCNTs, particle shape and the interactions of the two particles according to the Debye equation and the Maxwell–Garnett mixing rule. The C@CIPs composites had a better absorbing property as RL < −4 dB in 4.6–17 GHz with thickness 0.6 mm as well as shielding property (maximum 12.7 dB) in 2–18 GHz. It indicated that C@CIPs might be an effective absorbing/shielding absorbent.
