Abstract

Al/Fe/Co doped ordered mesoporous carbon (OMC) composites have been synthesized by a facile method, and the influence of dopant on the electromagnetic (EM) and microwave absorption properties was investigated in the frequency range of 2-18GHz. Compared with Fe/Co-OMC composites, the Al-OMC nanocomposite played a great role in adjusting values and frequency dependence of complex permittivity, which gives rise to significant improved microwave absorption and reduced thickness of the corresponding paraffin wax composites. Reflection loss (RL) values less than-5dB and-10dB were obtained in the frequency range of 9.2-18GHz and 10.7-14.7GHz with a single thickness of 2.00mm, respectively. Such enhanced EM wave absorption property of the Al-OMC/paraffin wax composite was ascribed to its superior impedance matching characteristic. Thin thickness, broadband absorption microwave absorbers with Al doped OMC nanocomposites were obtained.
