Which of the following does NOT represent a property of carbon nanotubes useful in nanotechnology application?

a. high electrical conductivity
b. low thermal conductivity
c. high tensile strength
d. flexible under compression


b.
This statement is not true. Carbon nanotubes have extremely high thermal conductivity, which shows that thermal and electrical conductivity are interconnected. Nanotubes have the ability to carry large currents and also carry away the heat associated with large currents, making the maximum current density they carry large enough to rival the critical current densities of some superconductors.
