COMPOSITE MATERIAL HAVING A VERY LOW CONTENT OF CARBON-BASED NANOFILLERS, PROCESS FOR THE PREPARATION THEREOF AND USES THEREOF

摘要

A composite material containing a polymer composition and a very low concentration of carbon nanofillers, in particular carbon nanotubes, having improved mechanical properties. The method for producing said composite material and to the different uses thereof. The use of carbon nanofillers at a concentration of between 0.1 ppm and 99 ppm in order to improve mechanical properties, in particular the tensile properties of a polymer matrix encasing at least one polymer selected from a thermoplastic polymer alone or mixed with an elastomer resin base, while facilitating the shaping thereof into composite parts using any suitable technique, in particular injection, extrusion, compression or moulding, and while improving the electrostatic dissipation capability thereof.
