Nano-C Products: Carbon Nanotubes - Materials that power our world

Carbon Nanotubes

Single walled carbon nanotubes (SWCNT) manufactured with Nano-C’s unique combustion technology are currently available in multiple grades, types and forms. Nano-C’s APT and PT come in 2 grades. The 25 Series are on average <1 micron in length and the 200 Series are >1 micron. Each grade is available in powder form, a “wet-cake/paste” for ease of handling or as a highly purified ink.

Type Separated SWCNT

SWCNT produced by any method statistically will be made up of about 1/3 with metallic and 2/3 with semiconducting behaviour. Separation between both material types will enable applications such as thin-film transistors (semiconducting) and high-end transparent conducting films (metallic).

Nano-C is scaling up technology developed in the laboratory of Prof. Michael Strano in the Department of Chemical Engineering at the Massachusetts Institute of Technology (MIT) for which Nano-C has an exclusive license. Different from other sorting technologies, the MIT process eliminates the need for centrifugation and the use of density gradients, thus enabling operation at industrial scale.

Nano-C APT

The typical process for manufacturing SWCNT includes a carbon containing feedstock and a metal catalyst. The catalyst may be iron, nickel, cobalt, or combinations thereof. A metal catalyst is needed to initiate the growth of the SWCNT. Nano-C uses an iron-based catalyst. At high temperature and low pressure, and with precise process controls, the carbon feedstock is transformed into SWCNT, although some may be converted to amorphous carbon. If required by the application, the residual metal catalyst and amorphous carbon can be removed during purification.

Nano-C PT

To remove the metal catalyst and residual amorphous carbon, Nano-C purifies its SWCNT with an oxidative acid or sequences consisting of acid leaching and oxidation. This leads to nearly quantitative removal of these impurities. Purified material is used by customers with applications that allow for direct use of high-purity SWCNT. The –PT materials form the foundation of Nano-C’s C-Ink as described below.

Nano-C UPT

If an ultra high-level of surface quality is needed, Nano-C offers its Ultra-Purified form of SWCNT. This features a very high-temperature oxidation to remove excess amorphous carbon, followed by acid purification to remove catalyst.

Nano-C INK

A key innovation in Nano-C’s approach is the ability to produce a range of SWCNT inks for a range of applications without changing the fundamental dispersion chemistry. The different classes of inks are based on physical parameters. For example, an ink with extensive bundling of SWCNT and hence limited suspendability is still useful for applications such as battery electrodes or capacitors, whereas it is clearly not suitable for a transparent conductive coating application that needs individually suspended SWCNT.

Nano-C has pioneered the development of an ink using a proprietary formulation based on surfactant free dispersion of purified SWCNT in a water or solvent base. Typically, less than 2% of a proprietary molecular additive is used as a stabilizer. The key feature of the Nano-C ink is that these stabilizing additives can be removed at a later stage at temperatures compatible with plastic substrates.

The competing methods for suspending carbon nanotubes often involve the use of ionic or polymeric surfactants which leads to a non-conducting network of SWCNT (molecular polymer wrapping serving as insulator) or aggressive oxidative conditions resulting in damage to the electronic structure of the tubes; Nano-C’s ink-making process avoids both. The ink can be coated on a variety of surfaces using a number of techniques, including inkjet-printing, spin- or spray-coating, among others, thus serving as a general SWCNT platform for many applications.
