- Micrograph no
- 562
- Brief description
- Multi-walled carbon nanotube
- Keywords
- carbon, carbon nanotube, nanotube , polymer
- Categories
- Ceramic, Polymer
- System
- Carbon nanotube
- Composition
- Not specified
- Standard codes
- Reaction
- Processing
- This multi-walled nanotube was formed by catalytic cracking of a hydrocarbon gas
- Applications
- Carbon nanotubes may be considered a high performance mechanical polymer or an electrically conducting polymer but their greatest potential is in gas storage or as a filler in polymeric materials
- Sample preparation
- A dry, untreated aggregate of tubes has been used
- Technique
- Transmission electron microscopy (TEM)
- Length bar
- 3.2 nm
- Further information
- A variety of techniques may be used for the synthesis of carbon nanotubes. These include electrolysis of molten salts with a graphite cathode, chemical vapour deposition, and striking graphite with an electric arc. This multi-walled tube was produced by the catalytic cracking of a hydrocarbon gas. The graphitic planes are clearly visible and a thin layer of amorphous carbon can be seen on the outer surface of the tube.
