摘要

Electromagnetic and microwave absorbing properties of the ordered mesoporous carbon (OMC) doped by Ni ₂O ₃ nanoparticles absorber was investigated for the first time. A minimum reflection loss (RL) value of -39 dB at 10.9 GHz and a broad absorption band with the RL values under -10 dB is obtained in the whole Ku-band and X-band when the thickness is 2.0 mm and 2.8 mm, respectively. It showed far more excellent microwave absorbing properties with respect to undoped Ni ₂O ₃ OMC/paraffin composite. This phenomenon could be attributed to the strong cooperative effect between Ni ₂O ₃ and OMC.
