摘要：
The microwave absorbing properties and magnetic properties of as-grown Fe-filled carbon nanotubes(CNTs),annealed Fe-filled CNTs,and multi-walled CNTs were studied.Vibrating sample magnetometer results showed that the annealed Fe-filled CNTs have the weakest coercivity and strongest saturation magnetization among the three types CNTs,due to the presence of more ferromagneticα-Fe nanowires.After annealing,the values increased to 291.0 Oe and 28.0 emu/g and the samples showed excellent microwave absorbing properties.The reflection loss was over 5 dB between 11.6 GHz and 18 GHz with a maximum value of 10.8 dB for annealed Fe-filled CNTs(1.1 wt%)/epoxy composite.
