摘要：

Carbon nanofibers embedded with magnetic Fe3C nanoparticles have been synthesized using electrospinning technique, followed by one-step carbonization. By using Fe3C/C nanofibers as filler with 10% content, the sample can achieve a minimum reflection loss (RL) of -54.94 dB with a thickness of 1.36 mm, as well as the broad effective absorption bandwidth (EAB) can reach to 4.5 GHz (13.3-17.8 GHz) at the thickness of 1.55 mm. The superior properties might be due to the synergistic effects of dielectric loss, magnetic loss, multiple scattering and reflection. This work presents a facile and promising method to produce high performance microwave absorption materials with thin thickness, light weight and strong absorption. (C) 2019 Elsevier B.V.
