Résumé

Microwave absorption properties of onion-like carbons (OLC) have been studied in microwave frequency range. A consistent analysis of the electromagnetic (EM) attenuation provided by OLC-based suspensions with variable concentration of OLC has been carried out in Ka-band (26-37 GHz). The first study of spectral features of the given suspensions (7.2-28.6 volume percents of OLC stuff in vaseline) demonstrates that the percolation threshold of OLC is strongly dependent on the average nanocarbon cluster size. It has been found also that raising the annealing temperature of a precursor nanodiamond leads to the enhanced absorption ability of onion-like carbon. The way to manipulate the OLC absorption ability through the OLC cluster size and nanodiamond annealing temperature is proposed for producing the effective EM coatings.
