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

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.

Carbon nanotubes are different from other natural materials. The CNT’s incredibly small size and distinct properties allow it to do things other materials cannot do.
These special properties include increased electrical conductivity, thermal conductivity and tensile strength.
CNTs are extremely strong. A one-inch thick rope made of CNTs is 100 times stronger and 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?

The special properties of these tiny structures make CNTs useful for several current and future applications in the electronics field.

The possible uses for carbon nanotubes are still being explored. Some of the earliest and most successful uses have been in electronics.
Take a look at the chart on the next slide to see additional possibilities.
