Enhanced Microwave Absorption Properties of α-Fe₂O₃-Filled Ordered Mesoporous Carbon Nanorods.

ABSTRACT: A novel kind of α-Fe₂O₃-filled ordered mesoporous carbon nanorods has been synthesized by a facial hydrothermal method. Compared with dendritic α-Fe₂O₃ micropines, both a broader effective absorption range-from 10.5 GHz to 16.5 GHz with reflection loss (RL) less than -10 dB-and a thinner matching thickness of 2.0 mm have been achieved in the frequency range 2-18 GHz. The enhanced microwave absorption properties evaluated by the RL are attributed to the enhanced dielectric loss resulting from the intrinsic physical properties and special structures.
