Carbon Nanotubes and Nanofibers
|
|
| A family of engineered materials, -multi-walled carbon nanotubes and graphite nanofibers- are built "block-by-block" by the decomposition of carbon-containing gases over selected metal particles. Because of the utmost control in the manufacture, our products contain less than 1% impurities.

Multi-walled carbon Nanotubes. The carefully selected catalysts and the precise control of reaction conditions used for the manufacture of nanotubes result in a ultra-high purity product (>99.5 %) containing no nanoparticles or other common impurities. MWNT have average widths of 6 nm can be dispersed in a variety of solvents.

Platelet Graphite Nanofibers. Structures consisting of graphene sheets oriented perpendicular to the fiber growth axis in a configuration identical to that of a "stack of cards". These conformations expose only edges and possess unique properties. Image at right shows detail of the high purity materials available.

Carbon Nanochips are a newly developed product that consist of rolled sheets of graphite resulting in structures that resemble flattened nanotubes containing up to 6-8 layers. The distance between the inner layers can be a small as 0.34 nm, a value that is significantly narrower than of SWNT. A high resolution TEM micrograph is shown (right). Applications for these materials include FED, catalysis and photovoltaics.
