Carbon nanotubes—a girl’s best friend?
The diamond has long been
considered the hardest mineral
on earth until now!

What on earth are carbon nanotubes?
Carbon nanotubes (CNTs) are carbon structures with special properties that make them useful in a wide range of scientific and everyday applications.

There are four distinct forms of carbon:
Fullerene
GraphiteDiamond
Nanotube

Each form of carbon has its own unique properties determined by the arrangement of atoms within it.CNTs exist in three different forms. Even though the differences are very small, they cause each one to have its own unique properties.

CNTs are extremely strong. A one-inch thick rope made of CNTs is 100 times stronger than steel and is 1/6 the weight of steel. Can you imagine a building built with ropes instead of steel or an elephant on a platform supported by CNT ropes?

Its body is made from carbon composites instead of aluminum.
Nanotubes are stronger and lighter.

During the testing phase of the aircraft,
the wings were stressed
as much as they would be
in the worst conditions of
flight.

Updated September 2011
The wings were tested to 150% of the stress
that was expected
during flight. Planes are going to be lighter and
stronger because of
the tiny nanotubes.

This module is one of a series designed to introduce faculty and high school students to the basic concepts of nanotechnology. Each module includes a
PowerPoint presentation, discussion questions, and hands-on activities, when applicable.
The series was funded in part by:
The National Science Foundation
Grant DUE-0702976and the
Oklahoma Nanotechnology Education Initiative
