Kurzbeschreibung (Abstract)
Boron carbide (B4C) nanowires were synthesized on the surface of activated carbon felt (ACF) via an in situ thermal growth method. The microstructures of B4C nanowires were characterized by field emission scanning electron microscopy, transmission electron microscopy, and x-ray diffraction. The minimum reflection loss (RLmin) value of 40wt. % ACF@B4C hybrid materials amounts to -36.1 dB at 17.2GHz and the effective absorption bandwidth (RL < -10dB) is obtained over a high frequency range of 15.9-18GHz with an absorber layer thickness of 5mm. The obtained results prove that ACF@B4C hybrid materials have high potential as microwave absorbers with excellent microwave absorption property.
