Controlled fabrication of TiC nanocrystal clusters on surface of Ti particles for application in electromagnetic wave absorption

TiC nanoclusters densely grew on surface of metal Ti particles and were successfully prepared by a thermo-chemical reaction in acetone. The optimal synthesized conditions were 800 °C and 2.0 h under flowing acetone/Ar of 50 ml min^-1. The morphology, microstructure and constituent of as-prepared composites were characterized by complementary analytical techniques. The TiC nanoparticles/Ti-paraffin hybrids had distinct electromagnetic (EM) loss abilities in X-band. Theoretic analysis showed that the EM wave absorption behaviors obeyed impedance match and quarter-wave law. This work confirmed the as-prepared composites were promising candidates as EM wave absorbers.
