Temperature, atomic oxygen and outgassing effects on dielectric parameters and electrical properties of nanostructured composite carbon-based materials

This work deals with the dielectric properties of carbon-based nanostructured polymeric composite materials. A commercial epoxy matrix is currently filled with multiwalled carbon nanotubes, and final composite material characterized in terms of microwave behavior by means of the waveguide method. By following the guidelines of previous studies, the attention is focused on the changes induced by hard environmental conditions (hightemperature in ultra-highvacuum system) on the above mentioned properties. The results obtained in this preliminary research have outlined the intriguing properties ofcarbon nanostructures, establishing themselves as verypromising materials for the future aerospace composite technology
