Q. What are Carbon Nanotubes?

A. Carbon Nanotubes are molecular tubes about 10,000 times thinner than a human hair. They consist of rolled up sheets of carbon hexagons. They have remarkable electronic and mechanical properties that make them suitable for many applications.

Q. How Many Types of Carbon Nanotubes are produced?

A. There are several different types of Carbon Nanotubes produced. They are: Single Wall Carbon Nanotubes, Double Wall Carbon Nanotubes & Multi-Wall Carbon Nanotubes. Multi Wall Carbon Nanotubes come in various forms such as Bundled Carbon Nanotubes & Aligned Carbon Nanotubes.

Q. What are the differences between them?

A. Single Wall consists of one graphene layer rolled into a tube, Thus having a single wall. Double Wall consists of two graphene layers rolled up, one within the other; Thus having two walls. Multi-Wall consists of many layers of graphene rolled one within another. Aligned Nanotubes refer to the alignment of the individual nanotubes. Aligned nanotubes lie parallel to one another, all having the same alignment.

Q. What method do you use to create the Carbon Nanotubes?

A. We use a method called Chemical Vapor Deposition (CVD). This method is low cost and allows for us to create high purity products (90%-98%). With CVD, we can also control the diameter and length of the nanotubes produced.

Q. What is the difference between Powder and Dispersions?

A. Nanopowders tend to agglomerate. Dispersions are stable colloids of well separated nanoparticles. Dispersions also have less safety concerns. With dispersions, there is no need for special ventilation facilities. Dispersions are also easier to process for your product development.
