摘要

Porous SiO ₂ /3Al ₂ O ₃ ·2SiO ₂ ceramics decorated with carbon nanowires (CNWs) were manufactured by catalytic chemical vapor deposition (CCVD) for wide absorption band and high absorption application. The results show that the as-prepared CNWs grow uniformly in porous SiO ₂ /3Al ₂ O ₃ ·2SiO ₂ ceramics to form the three dimensional(3D) structure. The content of CNWs can be effectively controlled by changing the weight of catalyst, and the dielectric properties of CNWs-SiO ₂ /3Al ₂ O ₃ ·2SiO ₂ composite ceramics can be tuned. As expected, the CNWs-SiO ₂ /3Al ₂ O ₃ ·2SiO ₂ composite ceramics possess wonderful electromagnetic (EM) absorption properties due to the effects of conductive loss, impedance match and dipoles polarization. It can be concluded that the minimum reflection coefficient (RC _min ) of CNWs-SiO ₂ /3Al ₂ O ₃ ·2SiO ₂ composite ceramics reaches −31 dB at 9.1 GHz (which means 99.9% of EM wave powers are absorbed) and the effective absorption bandwidth (EAB) covers the whole X-band (8.2–12.4 GHz) at the thickness of 5.0 mm.
