Abstract: The present invention describes a composite material based on a polymer matrix in which carbon nanotubes are dispersed, and also a process for obtaining such a material. The process of the invention is based on the use, as compatibilizer, of a block copolymer obtained by controlled radical polymerization and having at least one block bearing acid and/or anhydride functions. Such a compatibilizer makes it possible to control and optimize the interfacial interactions and thus to obtain a stable composite material that has good properties for use.
