Fabrication of doped carbon nanotubes by template synthesis using nanoporous alumina as template

Abstract

There is a considerable need to develop new synthetic methods for fabricating CNTs which are more biocompatible, addressing issues such as elimination of catalysts, increasing CNT water solubility and adjusting optimal diameters and lengths. Template synthesis using nanoporous alumina membrane is recognised as an elegant approach to fabricate CNTs with controlled diameters, length and shapes suitable for many applications. In this study we present the template synthesis of multi walled CNTs with controlled physical and chemical properties to demonstrate fabrication of biocompatible CNTs with minor toxicity to the biological system.
