Abstract

TiC nanowires were synthesized by chloride-assisted carbothermal reaction, using sucrose, TiO₂ and NaCl as precursors and Ni(NO ₃)₂·6H₂O as a catalyst. The TiC nanowires have specific surface areas of 186.7 m² g^-1 with a diameter of 200-400 nm and length of dozens micrometers. The hybrids of TiC nanowires/paraffin exhibited distinct electromagnetic wave absorbing ability in X-band (8.2-12.4 GHz). The optimal reflection loss (RL) of -51 dB at 11.8 GHz and the bandwidth of 3.0 GHz (RL < -10 dB) was achieved when the thickness is 1.7 mm. The optimal reflection loss and matching thickness were determined by the impedance match and quarter-wavelength law.
