• wide band dielectric spectroscopy

The wide band dielectric spectroscopy analysis of the 1.5% multi walled carbon nanotube (MWNT) contain and 20% polyamide 6 (PA6) nanowebs obtained by three different treatments applied to the MWNTs (chemical, mechanical and mixed) was investigated. A morphological analysis of the samples was carried out using the scanning electron microscopy (SEM) and atomic force microscopy (AFM) principles. The evolution of the dielectric constant (Eps'), imaginary permittivity (Eps ''), dissipation factor (Tan delta) and the conductivity modulus were analysed, both from an experimental and a theoretical point of view.
