Abstract

Mg/Fe layered double oxide (LDO)/carbon nanohelix composites were prepared by an in situ chemical vapor deposition with Mg/Fe layered double hydroxides as catalysts and ethanol as carbon sources. The as-synthesized products were characterized using an X-ray diffractometer, field emission electron microscope, transmission electron microscope, energy-dispersive spectroscope, Raman spectroscope, vibrating sample magnetometer and vector network analyzer. It was found that helical carbon nanotubes deposited on two sides of Mg/Fe LDO flakes. A minimum reflection loss (RL) of -35.0 dB was observed at 11.9 GHz for Mg/Fe LDO/carbon nanohelix composites with a thickness of 3.0 mm, and the effective absorption frequency (RL < -10 dB) ranged from 10.1 to 15.3 GHz. The absorbing performance of the Mg/Fe LDO/carbon nanohelix composites was better than that of Mg/Fe LDOs.
