There is growing interest in the use of nanocomposites based on carbon nanotubes (CNT) due to their excellent mechanical, thermal and electrical properties. The electromagnetic characteristics of nanocomposites with different types of multi-walled carbon nanotubes were investigated. CNTs with different geometries (length and diameter) were chosen in order to analyze the effect of the geometrical parameters on the electromagnetic properties. Nanocomposites with various percentages of CNT were made and the number of CNTs per cm3 in the composite was computed. CNTs were characterized by Field Emission Scanning Electron Miscroscopy (FESEM) and Raman spectroscopy. The complex permittivity of the NCs was measured with two different techniques, and the variation of the permittivity with the number of CNT per cm3 was investigated.
