摘要

A series of Co_(0.6)Cu_(0.16)Ni_(0.24)Fe_2O_4/multi-walled carbon nanotube/polypyrrole (CCNF/MWCNT/PPy) composites were prepared by the method of inverse micro-emulsion polymerization. The structures, morphologies and electromagnetic properties of the as-prepared samples were characterized. The results showed that PPy coated on the surface of MWCNTs evenly and its thickness was about 15～30 nm. The saturation magnetization of CCNF/MWCNT/PPy composite enhanced with the increase of mass fraction of CCNF/MWCNT composite (ω_(CIM)). In the range of 2～18 GHz, the minimum of reflection loss reached -23.06 dB, and available bandwidth was 4.21 GHz for the CCNF/MWCNT/PPy composite with 50% ω_(CIM). Hence, the CCNF/MWCNT/PPy composites are of great significance as an advanced microwave absorbing material in high frequency.
