We report a facile strategy to prepare a carbon microtube (CMT)/Fe3O4 nanocomposite with superior performance. The Fe3O4 nanoparticles obtained are about 400 nm in size and homogeneously anchor around the CMTs. The results show that the maximum reflection loss of the CMT/Fe3O4 nanocomposite is about -40 dB at 10.64 GHz and the effective absorbing band width is about 4 GHz with a thickness of 2.0 mm, highlighting the importance of the CMTs with nanomagnetic particles for wave-absorbing applications.
