AbstractThe strength and conductivity of carbon nanotubes make them attractive materials for incorporation into composite materials for use in electrically lossy structures. Applications could include light-weight structures that are absorptive of radio and microwave signals. We have derivatised multi-walled nanotubes by acid treatment, formed them into layers on resistor-like chips, and then subjected these to dielectric characterization between 200 Hz and 1.8 GHz. Especially in the case of thicker layers, a highly-frequency-dependent behavior was observed. This was reduced when the electrode contacts were improved. © 2006 IEEE.
