摘要：
Coiled carbon nanotubes (CCNTs) were coated by CoFe2O4 (CFO) nanoparticles to form the CCNTs/CFO composites. The phase composition, morphology, electrical and magnetic performances of the composites were characterized by means of modern analytical techniques. The results indicated that the conductivity and magnetic performances of the samples were related to their compositions. The CCNTs/CFO composite with omega(CCNT)/omega(CFO) of 0.4 exhibited the best microwave absorption property in the prepared samples, whose minimum reflection loss was about - 14 dB in the frequency range of 2-18 GHz for a layer of 2.5-3.0 mm thickness, and the available bandwidth corresponding to RL less than -10 dB can reach 4.0 GHz. Hence, the obtained composite could be used as a new candidate for selective frequency shielding and lightweight microwave absorbing material. (C) 2016 Elsevier Ltd and Techna Group S.r.l.
