text: Carbon nanotubes (CNTs) have attracted much attention because of their materials properties, including a high elastic modulus (~1–2 TPa), a high tensile strength (~13–53 GPa), and a high conductivity (metallic tubes can theoretically carry an electric current density of 4×109 A/cm2, which is ~1000 times higher than for other metals such as copper).
