Dielectric Properties of Carbon Nanotubes-Unsaturated Polyester Nanocomposites

Carbon nanotube based unsaturated polyester resin composites have been fabricated using sonication principle distribution behavior of carbon nanotubes in the resin matrix was examined through Scanning Electron Microscopy. Dielectric properties have been measured by using (impedance analyzer Agilent 4294 A), were measured impedance, dielectric constant and dissipation factor as a function of CNTs loading and frequency. Results showed that the dielectric constant, dissipation factor are increased with increased the concentrate ion of additional carbon nanotubes and frequency of applied electrical field and decreased with the increase of frequency.
