Nanotubes

Nanotubes

1. Properties

   • Length-to-diameter ratio of up to 132,000,000:1
   • The strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively
   • Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation
   • An inner nanotube core may slide, almost without friction, within its outer nanotube shell, creating an atomically perfect linear or rotational bearing
   • Very good thermal conductors

2. Potential Applications

   • Biomedical-bone tissue engineering
   • Structural- combat jackets and space elevators
   • Acoustics-such as loudspeaker and earphone
   • Electrical cables,circuits and wires
   • Environmental remediation-A CNT nano-structured sponge (nanosponge) containing sulfur and iron is more effective at soaking up water contaminants such as oil, fertilizers, pesticides and pharmaceuticals
