Composite of Matter for Multiwalled Carbon Nanotubes    

Innovative carbon nanotechnology solutions - new polymeric materials with many applications.

Overview

Taking advantage of our ability to manipulate catalysts we have developed unique products:

- Multiwalled Carbon Nanotubes (MWCNT)
- Platelet Graphite Nanofibers (PGNF)
- Carbon Nanochips (CNC)

Multiwalled Carbon Nanotubes (MWCNT)
High purity materials 99.3% as produced. They are generated from CO and do not form “bundles” like those grown from either C2H4 or C2H2. Soaking in dilute acid yields 99.9% purity.

Advantages of our process for MWCNT manufacture:
Pressure: 1 atm
Temperature: <600°C
Catalyst: Inexpensive
CO Conversion: ~ 80%
Rate: 125 g/h
Purity: >99%
Projected cost using CO: $18/kg
Projected cost using Natural Gas: $4/kg
Easily dispersed in various aqueous and organic solvents

Graphite Nanofibers (GNF)
P-GNF consist of stacked graphene layers. These materials have applications in gas and liquid separations, catalysis, Li-ion batteries and fuel cells.

Carbon Nanochips (CNC)
These new materials have applications in the synthesis of fine chemicals, pharmaceuticals, photo-voltaics etc. CML has the first applications in this area.

Carbon Nanochips (CNC)
CNC consist of rolled graphite structures having edges exposed. Carbon Nanochips are produced by treating GNF at about 2500°C in argon. The materials have an excellent performance as electrodes for Li-ion batteries and for catalytic oxidative hydrogenation reactions.

Primary Application of the Technology

MWCNT are excellent fillers because they are thin, long and electrically conductive.
Incorporation of as little as ~1 wt% MWCNT results in electrically conductive polymers.
In contrast, with powdered fillers a minimum of 35 wt% is required.
In the form of a film, the product is usually transparent and strong.
These new polymeric materials have many other applications.
