Microwave Properties of Multiwall Carbon Nanotubes filled Polymers

Résumé

The microwave properties of particulate polymer composites are of great practical importance. It is know that the dielectric response can be varied over a wide range by an appropriate choice of the shape, size and the connectivity of the constituents in the polymeric matrix. In this study, we will explore, at microwe frequencies, the effect of the strong anisometry (length to diameter ratio) of the multi-wall carbon nanotube MWNT when they are dispersed in an epoxy matrix. The experimental data are examined as function of the nanotube content, the temperature and the presence or not of a non-ionic surfactant (Tergitol NP7) The main results imply attractive interactions between the carbon nanotubes inducing the formation of the agglomerates that are observed by atomic force microscopy AFM, even in the presence of surfactant.
