During the last two decades, both single-walled and multi-walled CNTs probably represented the hottest research topic concerning materials science, equally from a fundamental and from an applicative point of view. Research on CNT synthesis, combined with basic understanding on growth phenomena, contributed to the development of a well controlled process and, thanks to this, the CNT production is now mature and ready for industrialization. Moreover, CNT application and inte- gration in very different systems, from nanoelectronics to optics, from biosensing to reinforcing in nanocomposites, was extensively demonstrated. There is a prevailing opinion among the research community that CNTs are now ready for application in everyday world. This book provides an (obviously not exhaus- tive) overview on some of the amazing possible applications of CNT-based materials in the near future. Some interesting topics concerning CNT surface treatment and in- tegration with other materials are covered, both from a theoretical and from an exper- imental point of view. Particular emphasis is devoted to the application of carbon nanostructures as reinforcements in nanocomposites. In fact, this field currently ap- pears as the most promising for the immediate market application, since the tailoring of material characteristics with CNT integration could open new astonishing possibili- ties in materials science.
