ince discovered in 1991, carbon nanotubes (CNTs) have drawn a great deal of attention as fantastic, pioneering materials for a wide range of
potential applications such as field emission devices, advanced nanocomposites, secondary batteries, fuel cells, supercapacitors, hydrogen
storage materials, nanoelectronics, nanoscale sensors, biological applications, etc. Such a great interest in the CNTs is attributed to their unique
structures and properties: high aspect ratios of small diameters (1~tens of nm) to extended lengths (µm~mm); duality of electrical properties being
semiconducting or metallic, depending on their structures; superior mechanical strength; excellent thermal conductivity; chemical inertness.
The CNTs can be usually classified into three different types of structures by their number of walls: single-walled (SWCNTs); double-walled
(DWCNTs); multi-walled (MWCNTs).
They can be produced mainly by electric arc methods, laser evaporation, and chemical vapor deposition (CVD).
