Surface functionalization of carbon nanotubes: fabrication and applications


Carbon nanotubes (CNT)s show exceptional one-dimensional π-electron conjugation, mechanical strength, high chemical and thermal stability, which make them very attractive for use in many applications. CNTs intrinsically tend to hold together as ropes and bundles due to van der Waals interactions. The prevention of such behavior has been investigated by testing a variety of surface modification methods. The functionalized CNTs present enhanced properties enabling facile production of novel nanomaterials and nanodevices. The functionalization of CNTs could improve their chemical compatibility and dissolution properties, which would enable both a wider characterization and consequent chemical reactivity. This review aims to provide a brief synopsis of CNT functionalization and highlights recent developments in the functionalization of CNTs and their applications.
