摘要	Microwave frequency (2-18 GHz) dielectric response has been investigated in the carbon-coated cubic TiC nanoparticles embedded in paraffin matrix with different weight fractions. DC conductivity measurements showed that the TiC nanocubes/paraffin composites have a percolation threshold of about 30 wt%. Absorption property was found to be improved with increasing mass ratio in the present system, up to a mass ratio of 50 wt%. Reflection loss exceeding -20 dB in the frequency range of 6-16 GHz, with layer thicknesses from 2 to 4 mm, was found in the 50 wt% loaded sample. TiC nanocube/paraffin composite with a proper mass ratio can be very good prospective microwave absorption agent. (C) 2010 Elsevier B.V. All rights reserved.
